Sort of a netbook anyway... The Alienware M11x just came out of CES and it is beautiful. This 11" piece of delicious is going to come in at a sub-$1000 price point and be able to crank through all of your games. It can even play Crysis at 50fps.
Hopefully more to come on the M11x- I'm trying to get some more info for you guys ASAP.
You can check out their preview page here - but there ain't too much there.
