IMO, until the ipad gets this, which is entirely possible, it will remain more of a toy than a tool, and all these commercials will be nothing but fodder for the haters.
there's nothing wrong with toys, and this is a nice one, but these lines about doctors, CEOs, etc., are just plain ridiculous.
Hummm... hardly from what I've seen. I know in my industry, iPads ares starting to be integrated into production systems for monitoring and control purposes. Plus, I have seen doctors using them.
Yes... they are a great toy. But the portability make them great for light duty tasks in business.
If we get a real file system in iOS 5 with could based storage and sharing, the iPad will get even more important in business.

How so. Please elaborate?
The decryption keys are everywhere and not top secret. Each iPod and iTunes has access to them. If you can get your hands on them you have something like hymn or FairKeys. Where does one get the encryption key?
EDIT: BTW I'm quite serious, if I got it wrong please help me understand where you're coming from.

No, you are WAAAAY off base.
The encryption key is public, the decryption key is private. The decryption key used in iTunes is hidden away to the very best of Apple's ability from the eyes of prying hackers. (at least, one assumes so - it's illegal for me to even try and confirm that.... thanks DCMA)
If I want to exchange confidential information with someone, I am going to need their public key. They can send this to me unencrypted (normally as part of a "certificate" to prove who they are at the same time...). I then use this key to encrypt the secret message, and send the encrypted message to them. They in turn can decrypt this message by using their private key....
Normally, the messages exchanged in this manner are actually symmetric keys (keys that can be used for encrypting and decypting a message). This is certainly the case for iTunes, which uses AES, a symmetric encryption system to encode it's media files.
Contrary to what you seem to think, the keys in iTunes are not freely available. Both the private assymetric key, used to communicate with the server (to obtain the symmetric keys) and all of the symmetric keys, used to decrypt the actual media files, are hidden inside iTunes. Try looking for them on your harddrive, I promise you that you won't find them (unless you are an expert pirate with a few months of your time where you have nothing better to do....)
BTW, that article that you linked earlier about FairPlay has internal consistency problems. If what it says about retrieving keys from the Apple Store is correct, then what it says about VLC can NOT be correct. one or the other is wrong. My money is on the info about retreiving keys is wrong. I do this stuff for a living, and it's certainly NOT how I would do it....

but I really thought the MacBook Air was going to be the "One more thing.." (which they didn't do.)
Since I was just thinking of upgrading my router from a Linksys to Airport Extreme, the announcement of Time Capsule was a welcome surprise. The pricing is pretty competitive when you consider what a 1 TB external firewire + Airport Extreme router would cost. (Although I do like the Drobo a lot, its pretty expensive once you add drives in it.) Time Capsule will be nice for Time Machine on both my iMac and MacBook.
Apple TV got off life support today. The iTunes movie rental announcement is HUGE, considering that ALL the major movie studios are onboard. It supports HD (720p is OK by me for now) and 5.1 surround sound, and doesn't require a computer for purchases or rentals. Too bad I don't have a widescreen HDTV, or I may actually buy one, but at least I can rent movies for my MacBook and/or iPod when I travel.
Since I don't own an iPhone or iPod Touch, the announcements here didn't do much for me. Tracking your location without a GPS is cool, and multiple messaging is fine, but to me, these are just evolutionary updates. Charging $20 for upgrading the iPod Touch is unfair, but might be related to accounting practices and reporting. I will be more excited about the iPhone and iPod Touch once the SDK comes out and third party apps are developed. (I want a SlingBox client.)
The MacBook Air is a really nice design. It shows what Apple is capable of pulling off. But, like a supermodel or Paris Hilton, they may nice to look at, but have limited usefulness beyond their outward appearance. You can't upgrade the hard drive, the processor is slower than what you can get on a MacBook Pro or even MacBook, and there are fewer ports to hook devices up to. The Air is the new fashion item for the rich and wannabe famous.
What I found interesting what WASN'T announced:
1) no 10.5.2 updates to fix Leopard bugs
2) no updates to MacBook or MacBook Pro. I REALLY thought those machines would get new slimmer designs and lose some weight (but not as radical as the MacBook Air), while retaining the current electronics.
3) nothing about the Mac Mini and any new updates.
But Steve Jobs did say at the end of the presentation that they still have 50 weeks to go for new announcements, so maybe something will happen with the other products during the year.
Overall, I would say it was an interesting MacWorld, but aside from Time Capsule and the movie rental announcement, there wasn't anything here that will make me buy new hardware right now.

Yes the iPad made a nice easy to use picture viewer once you had put the images on it from your real computer at home is what you are saying.
You could just of easy taken a laptop which read the CD images off directly onto the screen and no needed this new device whatsoever.
Just place the CD on any PC nearby, open either ReaddleDocs or GoodReader on the iPad and place it in WiFi mode, open your browser on your PC to access the iPad, and upload the images to it.

Well actually we know the TSA methods don't work because both of the incidents were from European airports that mirror what the TSA does. Added to the number of weapons that make it through TSA checkpoints, it's easy to see that the TSA does in fact not work to the extent that it is expected to.
All we know is that increased security screening is not perfect. Perhaps you can extrapolate the European experience (in this case) to the TSA... but that's as far as you can go.
I understood your rather simplistic attempt at game theory just fine. The problem remains that one side is not a rational actor. The command portion of terrorists have virtually nothing to lose with a botched attempt, and neither does the fanatic patsy. A 50/50 ratio isn't good enough for our security because the downside for both command and patsy are much smaller than the upside (from their perspective). The chances of failure need to be much higher in order to effectively deter terrorists.
Do you always start with the insulting tone (see bolding) when the debate isn't going your way? I would argue that both sides are rational actors, though both sides may also employ non-rational players. The higher echelons of terrorist organizations have shown themselves to very worried about being captured by the fact that they are so hard to catch. If they didn't care, they wouldn't be going to a great deal of trouble to avoid it. Therefore, to my mind, they are rational actors. That 50/50 number is one that I threw into the argument as an "for argument's sake". Please don't rely on it for anything factual. The TSA in fact catches more than 50% of their training/testing planted weapons. And yes, I think even if the the number was as low as 50/50 a rational actor would do everything... oh heck... I've already written all that - you've not presented anything else of substance in it's place, so I'll just save my typing finger....
Sacrificing these things is appropriate when there is a tangible gain. There hasn't been much of a tangible gain with TSA, and this is coming from the head of Israeli Security. We're paying a lot and getting almost nothing in return. Every year there's a new "standard" put out there to make it seem like TSA is doing something, but time and again security experts have lambasted TSA and its efforts as a dog and pony show.
Your own opinion of flying should be an example of how ridiculous things have gotten. If people now become disgruntled and irritated every time they fly, for perhaps marginal gains in security, then our methods have failed.
That's the funny thing. I've never actually said that the TSA is the best thing around. All I've said is that the TSA is doing something. That's all - that the TSA is doing something right. Not everything. Just something. Go back and look it up. Even the head of the Israeli security never said they were useless (as in doing nothing right). Just that it wasn't the best use of resources. Oh, and if you know Israelis (and I do), then you'll also know that there is another Israeli who knows just as much as that first fellow, and she thinks the TSA is doing things just fine.
It is difficult to prove, but you can make an educated guess about what the cause is. Other than the correlational evidence, there is no other good data to suggest that TSA has actually been effective. In no field is correlation enough to establish anything but correlation.
That's the problem with 90% of the decisions Governments make. All they have is correlational connections. Or incomplete causal relationships. Or... basically the best they can do is make an educated guess, and hope for the best.
No, that's not how it works. If you want to assert your idea as correct, the burden is on you to show that it is correct. I am going to try to poke holes in your reasoning, and it's up to you to show that my criticisms are invalid on the bases of logic and evidence.
No, on two counts. 1) You asserted "Our attempts at security are at best as good as Lisa's rock...". I countered your assertion by saying that the TSA must be doing something right, and used the stats on hijackings. I (to paraphrase you) "poked hole in your reasoning". You've presented nothing that counters my evidence, except to try mocking it as simplistic. If it is, then show how it is.... If my argument doesn't convince you. Then say so, and then leave it at that. I have my opinion, you have yours. But if you want me to change my opinion you had better do better. 2) I've forgotten - cr*p.
So far you've only cited correlation, which is not sufficient evidence for causation. You ignored my criticism based on military intervention, changing travel patterns, etc, and only want to trumpet your belief that correlation is enough. It's not. If you don't want to do more on Mac Rumors, then don't post anymore on this topic concerning this line of discussion.
You are right correlations don't show causation. But they are evidence for it. If you have evidence that shows otherwise, present it.

Have not watched the keynote. Not going to bother.
I'd like to see a bit more commitment from Apple (the company previously known as Apple Computers) on the computer side before I consider recomending any kind of Mac to people again.
You didn't watch the actual source of all of this information, but yet you feel that Apple might not be committed to the Mac anymore? Oye. Watch the first five minutes of it. :)
I think that those who think that SJ & Apple are beyond criticism merely confirm the excellent points you've raised in your post.
I find that most folks here are very critical of Apple and its products and don't usually hesitate to criticize where they feel appropriate. Just because not everyone participating in this thread don't agree with the OP's opinion that SJ is an arrogant SOB doesn't mean that everyone worships him either.
If all the iPhone mockups out there had missed the mark, the iPhone would be revolutionary, but there were quite a few that were based on the idea of a huge display and no keys.
I missed the markup where the full-screen video iPod was combined with the iPhone into on device.
The modest memory, for one, and for another the absence of 3G which is somewhat of a shocker - 3G has been a staple of top-of-the-line phones for years now.
Welcome to America. We're just now getting 3G (in regards to GSM networks, anyhow).
If not the business market, then who? It can't be kids, as it has no games, and allegedly no support for custom ringtones. It can't be business users, since they'll want Outlook or Lotus Notes sync, and possibly a navigator, and they'll most definitely not want to use frickin' iTunes to sync up. Which leaves, I dunno... Mac enthusiasts and 30-somethings who are hoping for 15 minutes of fame by the watercooler? He did say his goal was 10 million units.[/QUOTE]

I like both Windows 7 and OSX 10.6.7 right now.
What I don't like about Windows 7 is the registry.
and what I don't like about OSX is the UI is starting to look old and that there is no native AVCHD support.
I don't think MS is going to get rid of the registry in Windows 8 but I can hope that they do. I also don't think Apple will make a major UI change with their OS until OS 11 but I have been wrong before.
Apple could very well be holding out until its final preview to show off some radical new UI changes.

You forgot something. You are comparing diesel to unleaded even in hybrid form. You need to compare the generators (unlead to unlead). Now image if those very high gas mileage diesel running as a hybrid.
The problem with battery right now is we are still working on a break threw. When we finally get a true break threw in battery technology I can see things really taking off.
Batteries are very efficient at story power. problem is they are a little on the heavy side but we are getting better at it.
Modern diesel hatchbacks like the Golf TDI (Euro engines, not the US-spec) can exceed 50-60mpg (http://www.volkswagen.co.uk/new/golf-vi/which-model/engines/fuel-consumption). The Volt is harder to measure because it's a plugin, so some power comes from the grid. GM's own webiste is rather mealymouthed about fuel economy. At one point they claimed over 200mpg (http://en.wikipedia.org/wiki/Chevrolet_Volt), but that included a full batery charge from the grid. Using only its onboard generator it gets about 50mpg (http://www.greencarreports.com/blog/1044209_now-we-know-2011-chevrolet-volt-will-get-50-mpg-in-gas-mode). So all the extra tech essentially fails to improve on a diesel. The plugin feature may actually make the car less green/efficient if you get the juice from a dirty or inefficient power plant.
I'd really like to agree with you, believe me. But the reason I'm skeptical is that we have no proof that a battery "breakthrough" is really on the horizon. I read somewhere that the overall efficiency of an electric car is currently only about 5-7% greater than a gasoline-powered car (EDIT here (http://auto.howstuffworks.com/fuel-efficiency/alternative-fuels/fuel-cell4.htm) is a link for those numbers, but admittedly not a very good one). The energy efficiency of batteries is reasonably good, but they are still too big and heavy, as well as being expensive and dirty to manufacture. And again, electric cars are only as good as the powerplant they get power from, and that is where the biggest efficiency loss comes into play.
As for the mass rail system. You might be thinking of the east coast. Trying coming to some city west of the Mississippi and you will see how little rail they have and we just do not have any good way to put a rail system in. It is very costly to retrofit those system in and it is a very slow process. Slowly it is happening but really the system that was designed in the past was based around people driving their own personal cars around. That was 40+ years ago that was put in so now it is harder to do put it in now.
It's less logistics than politics, sadly. And you are right, it's not cheap. But we have to do it eventually. Moving to dependence on our interstates and letting passenger rail services atrophy was a mistake, and now we will be forced to fall back on our rail networks more.
Electric cars (that are able to fully charge in under 20 minutes) subsidized by a solar panel roof is the future. Don't think a 300 mile range would be out of the question (within a few years) and would def work even in large countries like the U.S.
If you look here, they are talking 5 minutes for 70% charge of the car, even though it is currently only a short range vehicle.

Two issues with that: First, solar panels are neither practical in most states, nor to they really have the lifespan to do more than break-even interms of paying for the,mselves.
Second, that juice still has to come from the power plants, with all the attendant downsides.
I really don't want to sound like a naysayer, but "going green" has become so fashionable that I think people are ignoring the engineering realities. We want whizz-bang electrics and hybrids when a simple diesel would be much easier to get on the market literally today and dramatically decrease our national fuel consumption (and dependence on oil imports) while we work to perfect the next step in alternative fuel vehicles. One step at a time, people!
Why are we letting Congress and the EPA block sales of diesels here that could be used in everyday cars in addition to series hybrids?
The problem with battery right now is we are still working on a break threw. When we finally get a true break threw in battery technology I can see things really taking off.
Batteries are very efficient at story power. problem is they are a little on the heavy side but we are getting better at it.
Modern diesel hatchbacks like the Golf TDI (Euro engines, not the US-spec) can exceed 50-60mpg (http://www.volkswagen.co.uk/new/golf-vi/which-model/engines/fuel-consumption). The Volt is harder to measure because it's a plugin, so some power comes from the grid. GM's own webiste is rather mealymouthed about fuel economy. At one point they claimed over 200mpg (http://en.wikipedia.org/wiki/Chevrolet_Volt), but that included a full batery charge from the grid. Using only its onboard generator it gets about 50mpg (http://www.greencarreports.com/blog/1044209_now-we-know-2011-chevrolet-volt-will-get-50-mpg-in-gas-mode). So all the extra tech essentially fails to improve on a diesel. The plugin feature may actually make the car less green/efficient if you get the juice from a dirty or inefficient power plant.

As stupid as they are, probably not. They're happy with having the most market share, why should they bother changing anything?
That's understandable.
But, when it's as easy to get a virus as downloading a banner ad from a website that you visit ( sometimes even legitimate ones) using IE with ActiveX enabled, then *maybe* a stronger security model is called for.
These days, if you're running Windows and don't have at least a good antivirus, antispyware and (can't hurt) firewall, you're almost assured of getting infected somehow. I see it all the time at work - we have people coming in paying hundreds to have us remove viruses and to install a new antivirus program, because they didn't know the old one expired.
MS has done a lot in the security department; much more than Apple has ever done in the last years. But yes, Windows needed it; Mac OS didn't.
The extent to which viruses appear on windows has decreased but yeah, there are still a lot of viruses and one can easily be caught up in that situation.
If Microsoft was smart, they'd even *consider* doing this - I hate to say it, but look at Mac users - even though we're not immune to potential viruses in the future, how long has OS X been around, and how much malware is out there to infect it? Maybe 5-10 programs? UNIX just has that stronger security model...
I don't think its about malware/viruses.
Mac OS X provides all the features one needs (as a pro and as a consumer - not all though). UNIX is one of the biggest advantages of Mac OS X. Back in the day, the nerd crowd went apple mainly because of Mac OS X's UNIX capabilities. The times have changed though. But I think if Windows 8 comes out as a UNIX compliant, its going to be tough for Apple to reside in the pro-nerd market.
That doesn't mean apple is going to lose marketshare. But that kind of competition is going to be a major setback to apple in reference to how 'expensive' the mac machines are.
That said, and again, times have changed. Apple charges for the complete ecosystem rather than machine by machine OR software by software costs.
I wish windows goes UNIX to attain dead heat with Mac OS X.
I'll be the first one to jump and get a windows laptop (won't leave my macintosh though, ever ;)).

On your first point: It is also the company that came out with the iphone 4 and its antenna problems.
yes the tragic design flaw that only existed in the US in the areas where ATT service blows.
Same design flaw recently confirmed on the HTC even
As for these rumors, I don't believe said site on anything. Their record is so spotty it is a joke. Also if Apple was going to release a CDMA phone why haven't they for countries like China where I is the dominate cell phone tech. Instead they went with the second place carrier who supports GSM. Even all the talk that they are hiring CDMA knowledged engineers which 'proves' they are working on a Verizon phone falls apart when you consider the unlocked, no exclusives iPad. So that staff could be working on the product.
I won't go so far as to say that a CDMA iPhone would never happen, or an LTE Verizon iPhone. I just do buy that it is coming this soon. For a number of reasons. And no one has shown me proof reasonable enough to think otherwise
