This is nothing new...
I used those devices in last year for my GCSE courwork (15-16 yrs old). I used them in a drinks cooler / heat thingy.
I won't ramble on about my product, but: The devices are called "Thermo electric coolers. i.e. TEC's
And they offer 3 functions.
1. The cool something.
2. They heat something.
3. They produce electricity.
This heat / cooling effect is called the Peltier effect (some French guy) and some people call these things peltiers etc.
They work, buy passing a relativly large current 3-20 amps, depending on wattage. to draw heat from one side to another basically. one side is -10 degrees c. The other is +80 degrees c. However, if you don't power them and instead create a temperature difference, i.e. stick ontop of a hot computer chip. You wil have set up a temperature gradient. So it will generate electricity. Typically you get around 4ma per 1 degree C. So nothing huge, unless they have refined them. So in this case, the bigger the delta T, the more power. I guess it could power a fan then! Seem's easily possilbe, but I wouldn't expect battery life to be much more than 30 mins at most extra. As 1 fan doesn't draw THAT much power!
Still a good idea though!
If anyone else has any questions, on how they work, images, tech drawing, or my product, i'm happy to answer them all!
BTW: Forgot to add, the generating electricity idea, from one of these, is called the "Seebeck Effect"

I'm hoping to see those OpenGL improvements significantly boost my Quake 1 fps on my MacBook.
hah! you are ridiculous, trying to play quake on an integrated graphics chip.
shoulda bought a macbook pro.
that said, for the money apple is charging, they could have definitely picked a low end dedicated graphics chip from ati or nvidia. shame on apple

Ping me if you are interested in a used GT120. It's only 5 months old or so, and I've got the receipt, etc.
Why do I want to sell? Under current conditions (Snow Leopard, applications etc) all my 3d apps default to the GT120 rather than my 4870 for rendering OpenGL, which slows my work in c4d and vue.
Oh, is there any way to change that? I do a lot of Maya and AE, will it affect those too? Like, If I were to use to hook up my third monitor to the GT120 and had a Maya window on it, would it use that or the 5870 to render? And if I had 3 monitors on my 5870 rather than 2, would that slow it down any?

I have used a Moto Xoom. Honeycomb requires you learn a new user interface. Instead of a nice seamless experience where you can get right in to using apps, you have to learn about the literally 3 or 4 different ways to trigger, dismiss, and access apps. If they're utilities, they're accessed one way. If they're apps, you've got an app menu and a desktop-style metaphor to try-- either works. It's confusing as hell. I mean, you can LEARN anything, but why would you want to.
Bottom line-- a Xoom is $800, it's far less functional, and it's far more confusing to use.
imo, if you've used any type of gadget before.. it's pretty easy to learn honeycomb within 5 mins of using it. hell i find it easier to use than a vcr. i think that some apple users, and i'm not saying you specifically, are just so used to ios or osx, that in a way.. before even trying out a new device.. they already pre judge it or are even biased.
i don't agree with your statement about the desire to learn new things also.. a lot of people love gaining new knowledge. why would you limit yourself like that? just years ago, i knew most things about how to efficiently use windows os, but my curiosity to learn osx made me a mbp owner.. you learn that some things have their purposes and usefulness.

The Thunderbolt port takes up no additional room. It replaces the miniDisplay port that is already on the machine.
Thunderbolt requires a discrete controller chip so it does take up space.

Glad I browse these forums at work. Just called my local Verizon and they're holding their last 16GB wifi for me. :D
I can't even get someone on craigslist to sell me their used one for this price!!
Ha, me too! It is just too good of a deal to pass up.

Not because of these commercials.
Honestly, neither of us is a marketing guru. However, we both do know a few things:
1) Apple's market share has been increasing recently (simultaneously with its Intel transition and introduction of new ads)
2) Apple recently claimed that it believes market share has been increasing partially because of these ads at its recent quarterly report.
3) Apple has committed millions of dollars to both developing these ads and paying for them to be seen on both popular television programming and internet websites.
I'm sure Apple and its marketing team knows better than we do - they wouldn't keep showing these ads if they believed they had a negative effect on the marketplace.
Then by what? Thes ads certainly arent hurting Apple.
Exactly - enlighten us. How do you know why its marketshare has increased as of late? Neither me nor freeny claim that its SOLELY because of the ads - but how can you prove that the ads haven't convinced 1 single switcher...?

This survey is seriously flawed. I've been unable to secure an AT&T iPad within the 3 stores near me.
Verizon iPad? They have them, at all combinations. Wi-Fi? Hit and Miss, but AT&T iPads are gone.
Maybe they made way more Verizon iPads? Seems like they would not??? Also, could be that so many iPhone customers in the US are AT&T, they are just naturally migrating to what they know.
I know... many here don't like AT&T, but does the average non-techie care?

Sadly, these "findings" really only say (or rather confirms the status quo) one thing to me.
Mac users are...PRETENTIOUS!
Lets see:
computer loyalty...zealot
Having degrees...rich
All other snob crap...flamboyantly rich and or wannabe rich
My favorite is:
computer-savvy and "early adopters"...LOL, clueless overbearing confidence based on ignorance.
Not only is the "genius bar" full of retards who help more retarded retards, but omg...if "computer savvy" means knowing how to use web applications that don't require install of real programs, then I'll grant "mac-users" that one.
Considering that nearly all "Pro IT" overwhelmingly used Windows not to mention that "gamers" are one of the most comptuer-savvy consumers, where the heck do computer-savvy Mac users come from? Those who can use FB, Twitter, Tumblr and other "early adopter software" vs. the old school, MS Office, ultra graphics games, Product Lifecyle Management Systems, and other real software? Yeah, I guess "young 20-somethings" will find out how using your Facebook / Web 2.0 computer skills in the real world will get your fired!

This is sort of off-topic, but is anyone else very amused at the voice they gave for the French John Hodgman? (http://www.apple.com/fr/getamac/)
it's the french actor who dubs David Schwimmer in Friends (and in some of his movies). Strange choice, but i guess his voice is easily recognizable.

It's not ready for the masses yet, but if you know even the slightest about tech (in its use, not in more technical aspects), it *really* is a superior device at the moment.
How does knowing something about tech make it a superior device? Are you basing it on something like a feature list? It is a highly inferior device because it is an inferior means of accomplishing the vast majority of tablet-related tasks as compared to the iPad. I'm not knocking Android by any means—it will continue to evolve and tablet offerings will improve—but in the tablet world it trails a considerable distance behind iOS and that is what matters most.
CR is obsolete.
By no means. They're just struggling to evolve with the products they review. I agree that they're poorly suited to review some of these more technical devices and I think their methodology renders many such reviews released by them fairly useless, but they serve a valuable purpose, it would be a shame to see this type of service go away, and I can't see how they've become obsolete to many folks out there.

Honestly, I never understood what was so frightening about talking to girls and trying to get a date, especially when it's someone you are just meeting and may never or rarely ever see again.
It can only go one of three ways: she could say yes and go on the date, say no but just be friends, or say hell no altogether.
No offense, but don't be such a chicken ****, just ask her!
Need a not-so-cheesy line that usually works for me? Say "I'm not usually this straightfoward, but you seem like a really interesting person and I was kind of hoping to get to know you better. Would you maybe like to go to [insert local place of interest here] with me on [available day of week] night?"
All your questions will be answered when she responds, then you can sulk or strut all the way home (depending on her response, of course). :)

It was announced, ... that with SP1, contacts, calendar and notes can now be synced through iTunes. BUT it doesn't! Anyone know what happened?
It does. You need to go into Tools --> Synch Services and enable calendar sync. I then restarted Outlook and iTunes, synced my iPhone (Info --> Advanced --> Replace info on this iPhone) and everything was there when I went into the calendar.
:apple:
EDIT: It also keeps the category colours from Outlook which is awesome, as Entourage never managed to do this.

The resale value of the purchased media drops to $0 the moment I buy it.
I generally agree with your thesis, restricted downloads should be a lot cheaper than new DVDs.
However, I believe that, for the most part, the market for used DVDs has dried up. I was doing pretty well buying movies and reselling them after I watched them (sort of Netflix w/o the subscription or deadlines) but now many of the movies I want to get rid of are often available for $2 + s/h on Amazon. So the only DVDs that sell for a decent price are rare or almost new movies...
Plenty of new DVDs of older movies for $10 or less at your local Target or Wally World.

This has nothing to do with Macs, or it might depending on which rumors you believe, but AMD's Clawhammer is coming out in the first quarter of 2003 and will likely be marketed as a 3400+ which would be higher than the PV at 3.2 Ghz. However, unless this chip gets used in the next Powermac revision (not likely, I know, but possible) then IBM better get that almost-too-good-to-be-true-Power4-mini-me out fast. I'm going to wait until October to see IBM's roadmap for any further speculation though. :)
