I would add that currently, avoid nVidia based ones as the chip is
much less supported than ATI chips (less 2D accels in X, no DRI 3D
support, no sleep support) and chose the 15" tipb with ATI Radeon M9
while it still exist on Apple catalog (this is really a great machine
with a very good video chip).

I may have a way to get sleep working on the nvidia based ones in
the future, depending if we manage to write an Open Firmware emulator
and figure out a few other issues with the new chipset, but this will
definitely take time.

Same problem with Airport Extreme in the new models, it's a Broadcom
chipset BCM94306 (PCI ID 4320) and Broadcom is well known to _not_
provide specs nor drivers to the linux comunity...
