Wouldn't using the "extra" electricity to power fans to decrease heat lead to less "extra" electricity???? :rolleyes: I hope they really think this through - and I'm sure they will. Of course powering fans isn't the only use for electricity.
Using the electricity to power fans would actually improve the efficiency if the thermoelectric device is placed between the processor and the fan. This would increase the thermal gradient and generate more power than if you were relying solely on heat dissipation to get your gradient.
The only problem with this solution is that high efficiency thermoelectric materials, by design, have low thermal conductivities, so it would not be a good idea to place this between the chip and the heat sink.
I am also skeptical about the claim of 30% efficiency. If we had thermoelectric materials that operated at that efficiency, we could all say goodbye to refrigerator compressors and turbine generators in favor of devices with no moving parts, higher reliability, and no CFCs.

Pages 1.0 is typical Apple. Anytime Apple puts out the first version of a product, its really a beta.
And, no, not necessarily because of bugs, but because it lacks the features or speed that a GM product should (ie OS 10.0)

Thx for the kind words guys/girls!
Could you post some screen shots? I might need to get tiger now.... :rolleyes:
The first post now holds 2 screenshots from a previous beta, just very slightly different from the current one. I will update them when i get home.
And indeed, you will need tiger now :D

Anything asthetically new in this version, or perhaps some new small features?
Nope. Nothing has changed in the UI and no noteable new features. As far as the super secret Leopard features, dongmin, they still remain super secret although the few new features in the preview are quite handy and have already become "How did I ever live without this?" kind of valuable to me.
I haven't noticed any major changes so far since the update. The issues I was having before persist though not as often and they are minor. The Leopard Preview is surprisingly stable unlike someone else's beta OS... no names ::cough::Microsoft::cough::
Parallels Desktop for Mac works fine under Leopard BEFORE installing the recently released Parallels Desktop beta update. If you install the Parallels Desktop beta update, colors in the app buttons/windows are distorted (http://img257.imageshack.us/img257/9683/snapshot20060831231144xj6.jpg) and this Leopard update does not seem to remedy that. Also, as stated above, the build number has changed (http://img258.imageshack.us/img258/978/snapshot20060831230551mc2.jpg).
iChat continues to be buggy during one way video chats and Parallels after the update continues to have its issues (besides the color distortion) but prior to the Parallels update, these issues were not present so Parallels Desktop 1848 seems to be completely compatible with the Leopard preview but not Parallels 1862.
I should also note that fan behavior on my MacBook Pro with the Leopard Developer Preview (10.5) is excellent... immensely better than with Tiger (10.4.7) but that was true even before I installed the Leopard Preview Update 1.0. :D

it wasn't until iOS and the apps store where you could do things like select a few recipes and make a shopping list did a PDA become useful
Recipe and shopping list Palm / Windows Mobile apps like Pocket Cook date from 2000. That one in particular won awards for years.
What you mean is, it wasn't until iOS that the mass public else took notice. Millions of us were surfing the web and using apps on PDAs, smartphones and tablets long before that.

Yes, the DVD-RW installation went fine for me :) It seems to work with iDVD 3 so I hope it works with your application. Good Luck!

Also For a 5th gen leaked ipod its pretty beaten up. I mean if i had somehow got a prototype i would keep it in a glass cabinet surrounded with cushions to stop it getting beat up. And wouldn't it run iOS5 if its the fifth generation? so why doesn't he tell us about that?

I haven't been able to find a SINGLE store that has the 16GB model. I've searched everywhere throughout the city and east bay. Anyways, all I've called have said the iPads are $299/$399/$499 with no contract.
Any 32GB left? If so where? At YYZ waiting to board my flight to SFO :)

Have they fixed the issue where the News Feed constantly reverts to "Live Feed" view even though you've selected "Status Updates"?
Because that problem right there is reason enough for me not to install it.

Apples and Oranges.
Same two shots just lit differently with off camera flash. Not sure I necessarily like either, just thought I'd post them. Figurative and literal contrast, I guess. Hopefully next weekend will be nice and I can get outside.

It probably depends on the specifics of the network you want to build, but overall, I always found it ridiculously easy to build a Mac OS network than a Windows one.
You may want to provide specific examples on how networking in OS X is 'insanely hard' as compared to Windows.
Even under Linux, it's easier than in Windows.

Kinect is more for the kids. They really enjoy Wii Sports so if there's an alternative (or blatant clone) with decent graphics for Move or Kinect, they'll be happy. It'll be interesting what 'Family' type games are released for both the new motion sensing systems. If you're going to wildly flail around the livingroom, you may as well do it in HD.
I personally just want a shiny black 360 to put under the livingroom telly. King of Fighters '98 Ultimate Match (and maybe '02 UM?), Mark of the Wolves and both Virtual-ON Oratario Tangram and Force. Just need Hori to do another run of Twin Sticks...
:apple:
My guess is Kinects is a way to keep from having to buy both a Wii and an 360. Of the system I like I like the 360 as it has more of the games that I like on it. Now if I had a family I could see getting the Kinects for it so the little kids would have something to play but then again I more than likely would put the 360 in another room since I would not want them seeing the Rated M games that I will play.

Cheers for your comments Abulia, I thought I'd give it a go anyway but you're right it didn't work. I just get the flashing power light, a loud beep then the Mac startup chime and a normal boot up. Strange. Oh well will wait for a fix from Apple I guess.
Or if you have a spare drive sitting around that you can boot from (like an external Firewire) for the sole purpose of installing the update.
