This isn't the latest Android device, but it's only around $50 and does most of the same things the iPad will do. It runs the Android OS version 2.2. The current version of the Android OS is 4.0. This is also a refurbished model but definitely very capable with a Dual Core Processor and 2GB of built-in storage.
