It has only been a few months since Asus announced the original PadFone Infinity, but the new version of the phone-tablet hybrid was just outed in Taiwan. This is a spec bump on the last PadFone, which moves from Snapdragon 600 to 800, but that's not all.
Just like the last PadFone, this one has a 5-inch 1080p screen, which is upped to a 10-inch display at the same resolution when the phone is in the tablet dock. Asus has taken the odd step of lowering the amount of internal storage, but adding a microSD card slot. The device now comes with 16 or 32GB of internal storage. The quad-core Snapdragon 800 will probably offer a bit of a performance boost, but so will the move to Android 4.2. The camera is still 13MP, but it has a new 3MP high-sensitivity mode sort of like the Ultrapixel camera on HTC devices.
The PadFone Infinity is not aimed at the US market. It has support for LTE 800/1800/2600, which won't work in the States. Pricing was announced at the equivalent of $640 for the phone and $240 for the tablet dock. That's a bit less than the last PadFone at launch. If you're interested, it will probably be on Amazon at some point. Well, or take a trip to Asia.
