If you want to check out Android OS, you can download and run a pre-configured Android OS Virtual Appliance installation within VirtualBox. You’ll need a torrent client to download the virtual machine itself, and of course Virtualbox to run it.

You can download Android OS VM here and get VirtualBox here, both are free downloads.

The Android VM was configured for an Eee-PC but runs fine inside of the VirtualBox environment. Running Android OS in a virtual machine is really helpful for anyone who wants to get their feet wet with Android development but doesn’t have an Android capable phone handy (and I’m not about to install Android on my iPhone), and it’s also nice to just play around with if you don’t have much experience with Android software.
