Easily one of the most-anticipated Android devices over the last year has been the Asus Padfone. First just a concept and eventually a developed product, Asus has finally pulled the wraps off if its shiny new form factor and the hardware that will release in just a couple of months. If you've been following the Padfone, you know it's an Ice Cream Sandwich smartphone that docks to become a full-fledged Android tablet. Asus had two new surprises at its launch event: one, the Padfone will be released in April, and two, they're not done defying conventions: they've added a Galaxy Note-style stylus that doubles as a Bluetooth headset. You read that right.
