Linux mint 12 worked well right off (poor 3d graphics at first).
Knoppix worked well, but no sound. (maybe it was off?)
Mepis had no sound and no wifi.
Most other distros wouldn't boot or were not very useful.
For $400 this notebook rocks.
Not without cons:
the sound is low (I wish the earphone jack worked correctly)
the screen has a rather narrow cone of visibility (a feature in a
crowd when privacy is desired?)
the keys are cheapo. one fell out and i pressed it back in.
the keys get caught up in the guide when pressing,(a single game of Open Arena would kill this kb) and they have no taper, but it is a full 3/4+ sized kb, with number pad.
there's no indicator for caps/numb lock.
There's a simple workaround for all the cons, so this set rocks, I'm happy.
