depends on the graphics chipset, most of the atom equipped have the intel gma950
it will do pixel shader 2.0
I own 2 of the asus models, the 1000HA and the 701. Never used either for games, doub't they'd do very well. Either are right at their limits playing DVD video, anything above that forget it.
the keyboards are a bit cramped but you get used to it pretty quick
where the atom equipped shine is a battery life and size/weight----4-5hrs of actual use and about 3.5 pounds
for $350 I'd buy another asus 1000 series no problem, its been a good little machine
only issue that bugs me is if you leave the battery connected and the power off it will drain itself in a few days anyway
the new ION chipset models are coming out soon I think, that will fix most of the graphics weaknesses
