Previous rumors have hinted that the new batch of PowerBooks will be thinner, faster and all-around better than the previous generation. So far the focus has been on the Intel aspects (and rightly so). But what if there are more hardware upgrades waiting in the wings. Case in point: LED displays in upcoming Sony, Toshiba, and Asustek laptops. Having a new low-voltage Intel processor and an LED screen would give the new 'Books a sizable battery advantage over the G4 models.
