Android: Android is the mobile operating system from Google. The software was originally built by a company called Android Inc, that was purchased by Google in 2005. From its modest debuts, Android has become a powerhouse that powers not only smartphones and tablet, but a host of other less high-profile devices and gadgets. Although Android is not a community-driven project, Google does release the source code as open-source under the Apache license. You can follow Ubergizmo on Android with Google Currents.

rooting: Rooting is essentially a process that allows users of smartphones, tablets or other devices running on Android to gain “superuser” access to the software. This will allow the user to perform administrative tasks such as writing to locations normally restricted by the system which in turn will allow for deeper customization. For iOS users, rooting on Android devices could be thought of as a close equivalent to jailbreaking your device. More info in Rooting for Android: What, why and how?
