Smartphones that transform into tablets are already a thing thanks to the creative minds at Asus, and soon PadFone users will have a third form factor to enjoy. The leaked images below reveal an upcoming “Asus Mobile Dock Keyboard” that turns the PadFone into an Android-powered notebook computer in a matter of seconds.

After unveiling a series of new devices at CES in Las Vegas just over two weeks ago, ASUS has now quietly launched a new Padfone variant in Taiwan. Named the Padfone E, the mid-range smartphone/tablet hybrid slots right between the Padfone Mini and Padfone X with regards to internals, however, unlike the other variants, the E is available to purchase in two colors — Johnnie Walker Black and Pearl White.

Earlier today, ASUS introduced us to a more compact, scaled-down and lightweight version of its flagship Padfone unit, entitled the ‘Padfone mini’. The 4-inch smartphone will now slot into the 7-inch tablet dock in a portrait orientation, as apposed to landscape one, which was typical for the two previous generations of this device.

According to recent leaks, rumors and speculation, ASUS is expected to unveil is latest Padfone variant, the Padfone X, in a press conference at the Consumer Electronics Show in Las Vegas later on today, and it looks as if AT&T will be the first U.S. carrier to launch the handset smartphone/tablet hybrid.

BARCELONA, MOBILE WORLD CONGRESS — Thanks to the original PadFone’s rather disappointing start, we thought the probability of seeing a successor at Mobile World Congress was slim at best. But we couldn’t be more wrong. Asus has just unveiled the PadFone Infinity, a 5-inch smartphone that transforms into a 10.1-inch tablet with the help of a clever docking station.

The device has some impressive specifications, including a 1080p display, a quad-core Snapdragon 600 processor, and a 13-megapixel camera. But do you really want a smartphone that transforms into a tablet? We went hands-on with the device to find out.
