This is the ASUS Padfone
Wow, so our theory and mockup turned out to be pretty much spot on: indeed, the oddly named ASUS Padfone does tuck itself into a shielded docking bay on the back of its companion tablet, and the latter's hinged cover appears to pop up upon releasing the latch. You can also just about make out the two ports inside which are likely to be HDMI and micro-USB -- one for driving the larger display, and the other for taking care of touch input while possibly sipping juice from an extra battery somewhere. Now, what we really like to know is which version of Android will be shipped (if ever) with this split-personality phone -- our money's on Ice Cream Sandwich, given that this flavor will happily cater both phone and tablet form factors later this year. That said, given the uniqueness of this product, ASUS could probably still get away with taking a step back and launch this as a Gingerbread tablet. Well, we shall dig up more answers for y'all tomorrow, and stay tuned for some sweet hands-on time.
