The Asus Padfone has been a long time in the making, but we should finally see the final design at Mobile World Congress on February 27th, according to a report from Paul O’Brien of Modaco. The first of its kind innovation allows the user to dock their smartphone into a tablet docking accessory for a larger viewing area.

Many recent reports keep claiming that the Padfone will feature Nvidia’s Tegra 3 processor, but the device was already spotted with a Snapdragon S4 (MSM8960) in some leaked benchmarks. Sean Hollister of The Verge also confirmed the Snapdragon S4 processor was included with the prototype unit that was being shown off at CES.

This could all change however because Asus is expected to reveal a redesigned Padfone that differs from the prototypes that have been shown so far. This means the physical design will be altered, most likely to remove the physical buttons since the Padfone is expected to ship with Android 4.0.

Another interesting feature of the Padfone is that it supports the Asus Transfomer keyboard dock. The prototype unit shown at CES supported the older TF101 dock, but we expect the redesigned unit to support the newer TF201 docking station that works with the Transformer Prime.

Overall, it looks like a pretty unique device that is sure to garner some attention thanks to its unique design. Ultimately, we think it will succeed or fail based on the exact retail pricing of the tablet accessory. Hopefully they can keep it under $ 150, similar to the mobile docking station of the Transformer Prime.
