ATi Mobility Radeon X800 XT
ATi has announced their newest highend graphics card for notebooks, the Mobility Radeon X800 XT. The chip uses the PCI Express interface, which currently isn't used in PowerBooks. The current PBs use the Mobility Radeon 9700 instead. A move to PCI Express and such a powerful graphics card would certainly make the current crop of PowerBooks more attractive, alas: Apple has never "just" upgraded the graphics card of a PowerBook, so this probably has to wait for another revision of the PowerBook, which isn't expected for some time to come.
