The Padfone gadget uses a 4.3-inch smartphone that docks inside a 10.1-inch tablet and has dynamic display switching, two batteries, Qualcomm processor, shared SIM card, a single hard drive, Android’s next generation operating system (Ice Cream Sandwich) all for about $900. Sounds neat but call me skeptical. Look for the Asus Padfone at the end of 2011.
