I think Apple really needs to incorporate some sort of screen improvement. Yes, they have the sexiest looking laptop, but it's time to kick it up a notch. These x-brite displays are not only sharper, but I recall seeing one with a non-glare model (not sure if it was Toshiba or Compaq).
The issue as others have mentioned, is battery life. From what I've read, the Centrino chip is pretty good in terms of speed and power consumption. Is there a PowerPC equivalent? On the upside, we have OSX.
