Barnes and Noble introduce eReader

Barnes and Noble have introduced an eReader based on Android (Google's mobile OS). It incorporates 3G and WiFi and has 2GB of memory and can take up to 16GB microSD cards.

The eReader known as the Nook can also "lend" books to other B&N eReaders for up to 14 days at a time.

It retails for $259 and is potentially a Kindle (from Amazon) killer.
