Just come across this Android LiveCD from some IRC channel, I found the introduction from the official web :
"Want to give Google Android a try, but don't feel like buying a T-Mobile G1/G2/G3? LiveAndroid lets you download a LiveCD disc image of the Google Android operating system. Just burn the image to a disc, stick it in a CD-ROM drive, and reboot your computer and you can check out Android without installing it or affecting any files on your PC."
This should be the great one. Malware or rootkit testing on Android? LOL
