our setup (Score 1)

I have a Dell Mini 9 running Ubuntu that I gave to my six year old to play with/break. On top of the usual install it's got ktuberling (mr. potato head), gcompris, and tuxpaint on it, those three keep her and our three year old amused for a bit. They've learned excellent trackpad skills, know how to user switch, type in passwords, type in words for games, play various elementary games, etc.
