Just in case it had slipped your mind, now is a pretty great time to be looking for a computer. Take this IdeaPad U150
from Lenovo which just started shipping, for instance. For $699 you can get a CULV processor, 3GB of RAM and a 250GB HDD stuffed inside a 3 pound, 0.75-inch thick enclosure, with a 11.6-inch 1366 x 768 display and Windows 7 Home Premium. Bump it up to $849 and you're looking at better internals all around, and while those Intel X4500 graphics might be holding you back performance-wise, the external looks and build quality of this thing almost make up for it.
