Does it need to be able to play the games? If not ...
If you want the tinyest laptop ever, take a look at
mine (ASUS s5n). At 2 and a half pounds, it's the greatest laptop for school... ever (Size comparison with my free iPod

) It's not the most powerful thing in the world (1.5GHz, 256MB ram, intel graphics) but for me, who just takes notes and compiles bits of C code all day, it's really all I need. Sometimes you forget if it's even in your back pack ;]
But if you need a laptop that can play harcore games, then I guess I can't help.
