iFixit got their hands on one of the first The New iPads (by Ghu that's an unwieldly name) yesterday and proceeded to take it apart. This is relevant to the recent discussion about tablets and power consumption. For comparison, I have here an HP Pavilion dm1-4010us notebook with 11.6 1336x768

Is the lack of air flow a good or bad thing? Are the new iPad going to make good hand warmers? Cheers. Steve. On Fri, 2012-03-16 at 10:17 -0400, Richard Pieri wrote: iFixit got their hands on one of the first The New iPads (by Ghu that's an unwieldly name) yesterday and proceeded to take it

Perhaps a better answer is something like a MicroOptical/GoogleGlasses display, which I imagine would require far less power. Lose the big display, and perhaps the rest of the device could be squeezed into a Twiddler-like chord keyboard. On Fri, Mar 16, 2012 at 2:49 PM, Tom Metro
