I figure why the CD/DVD drive was left out now - to further increase battery life again by about 45 minutes - including a solid-state-drive which I think the Air comes with would increase it even further, you don't have to have the drive heads spinning all the time. And 45Nm is even better; I'd be more than happy to pay for technology using that sort of technology - interesting.
I don't know if you've heard about the Xbox360 "red ring of death", but the 65Nm CPU is too large for the motherboard to handle, effectively overheating the console - taking that to 45Nm, which Microsoft still hasn't done yet and is "talking" about it, would decrease the failure rates from 36.6% to around 10%, which is a large decrease - and quite impressive too.
One thing Apple needs to include in its next iPods, laptops etc (and other hardware makers like Toshiba, Acer, Palm etc) is the addition of a non-Lithium-Ion battery. Not only do they need replacing after 400-500 charges but they're more at risk of dying quicker and can't be easily removed. Apple gives warranty on that (lifetime warranty, which is meant to be three years) and let it be removed without permission or supervision from Apple, and I guarantee the iPod sales would increase five times as much.
The processor, however, is significantly slower than the latest Intel Core 2 Duo processors used in other new notebooks. Performance is not necessarily an issue with Apple as it customizes its operating system to maximize performance out of any processor it uses.
That's right. It is a last-generation CPU. Still, a Core Duo is better than a Pentium 4 or Celeron (which I'm stuck with, unfortunately). Even the Celeron being at 3.0GHz it is comparable speeds to a 2.2GHz Intel Pentium 4 or AMD3200+ (the other processor manufacturer).
