Ubuntu Eee
Ubuntu Eee rocks.
If I had any misgivings about Ubuntu Eee before, they were largely unfounded. Ubuntu Eee turns my EeePC 701 4G into everything I want it to be. It's just...perfect. Sound works, Wifi works, camera works; and more than that, everything seems scaled to the right proportions. The 7" screen is still 7" but its use of the real estate is very sensible.
It's a new lease on life on my EeePC.
