The Android team have been busy and have released a LiveCD / LiveUSB version of Android for x86 platforms. The LiveAndroid allows you to burn a copy to a CD or stick it on a USB and boot right from it allowing the testing of the OS without having to make any changes to your system or create a partition.
The Android Team are also after your help in the following areas of the project:
LiveAndroid’s logo, Wallpaper, Mirror, Forum, Testing Hardware
So if you want to get involved head over to the Live Android Pages Here
When I have had a try ill give you an update on what I think!
Have you tried Live Android? What do you think?
