You've probably heard about the One Laptop Per Child program,
but if you haven't you can read more about it here:
http://www.laptop.org/
And on Redhat.com here:

Redhat has just made the Linux-based operation system available for download,
and you don't even have to install it since it's possible to run it directly from the (LiveCD) CD..

Haven't tested it myself yet, but it looks interesting so I'll probably give it a try tomorrow.
It's based on Fedora Core Linux and includes a simple Gecko based browser
(a special Opera version is also available), a word processor based on AbiWord,
web-based e-mail through Google's Gmail, VoIP and chat software,
audio and video player (Mplayer or Helix).

Looks like they didn't expect it to get very popular when they released it to the public..
