Rumor: MWSF PowerBook G4 Gets VBT, Possible 16" LCD


O'Grady's PowerPage is reporting that mock-ups of the next major PowerBook G4 revision, due to be introduced at MacWorld San Francisco in January 2003, will feature 'variable bus timing'.

The big news is that Apple has reportedly done significant work on the PowerBook's heat levels, increasing the effectiveness of heat transfer. Apple has also made design changes to the CPU's cooling system.

A mock-up of the next PowerBook's design had a different display from current models, according to the article, which may be a 16" LCD [although the mock-up - not a prototype - makes this an uncertainty]. Sony, for example, already offers a 16" screen. Displays will also be brighter, with new backlights for the LCD.

PowerPage sources claim VBT can effectively double battery life, through the CPU's use of 'smart' power management, which allow the processor to shift into high or low mode when performing routine, repetitive tasks, such as playing a DVD-ROM or audio CD.

Analysis: A 16" display (perhaps as a BTO 'Ultimate' PB G4 system), would certainly grab some attention. Given falling LCD prices (with a 19" LCD iMac supposedly around the corner), it would not be prohibitively expensive for Apple to implement either.

The cooling work suggests not only is Apple working on increasing the working life of internal components, but also that the new PowerBook (not be confused with next Wednesday's anticipated minor revision) may sport a seriously fast architecture and processor.

But the question remains: what will they make the case material out of? Better Airport reception is a must for the PB.
