Welcome to LiveAndroid, a LiveCD for Android running on x86 platforms.
Want to give Google Android a try, but don’t feel like buying a T-Mobile G1? 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.
You can also use the disc image in a virtualization application like VirtualBox, VMWare or Microsoft Virtual PC if you want to try the operating system without even rebooting your computer.
Download it for free right here. The uncompressed os ISO file is 157 Megabytes.
