Just as promised, today ASUS has made its new PadFone Infinity official in Taipei, and there are definitely no surprises in the specs. The main update here is obviously the 2.2GHz quad-core Snapdragon 800 SoC, along with the addition of a microSD slot plus a secondary microphone for noise cancellation. Unsurprisingly, the internal storage options have been lowered to 16GB and 32GB, which is understandable with that new storage expansion capability.

One very subtle change that we missed in the leaks is the new diamond cut on the metallic backside, which gives the phone a more premium and solid look than the original version. To accompany that, the new PadFone Infinity comes in two new color options: "Titanium Black" and "Platinum White."

The software has also been given a gentle facelift, courtesy of a more consistent design language throughout the system -- from the simplified icons to the UI of some of the built-in Android apps. Since this is based on Android 4.2 instead of 4.1 out of the box, we should also see some performance boost as well. The good news for existing users is that the original PadFone Infinity will also receive this update, but there's no time frame for the roll-out just yet.
