While watching Live.Twit.TV as they walk around early products show at CES on January 8th 2012 they stopped and talked with Lenovo and a guy was showing a ThinkPad Tablet 1838, it’s a 10.1″ Android 3.1 tablet. It has a lot of connections and ports along with a pen tool to writ on it. Also they can be setup for business and also be managed by an IT department.
