I'm blogging this since I didn't even know one thing about Android, but I see Android is being used for various library apps e.g. by Peter Godwin. This is a new white paper from EDUCAUSE in their "7 Things" series. I now know that "Android is a Linux-based, open-source operating system designed for use on cell phones, e-readers, tablet PCs, and other mobile devices."
