ASUS PadFone Infinity announced: 5-inch, 1080p display, Snapdragon 600 CPU and full HD tablet display

You may have heard a new PadFone was on the way -- it's not like ASUS has been dropping obvious hints or anything. In any case, surprise! ASUS just unveiled a new model, the PadFone Infinity. Like other PadFones, this is a handset that slips into a tablet-like dock, allowing you to make use of a bigger screen. This time, though, it ships with Android 4.2, and the display has grown from 4.7 inches to 5. The resolution is now 1080p (up from 720p), which comes out to 441 pixels per inch. Additionally, the tablet's 10.1-inch screen has a resolution of 1,920 x 1,200, up from 1,280 x 800 in the last-gen model. It's plenty bright, too, at 400 nits, but that's a slight step down from the last-gen model, which lit up to 500 nits.

What's more, the phone's gotten an upgrade on the inside: it now packs a quad-core, 1.7GHz Snapdragon 600 chip with an Adreno 320 GPU, some of the freshest components Qualcomm has to offer at the moment. Also on-board, you get 2GB of RAM to help boost performance, with your choice of either 32GB or 64GB of built-in storage. As far as connectivity, you're looking at EDGE, GPRS, GSM, WCDMA, LTE and DC-HSPA+, along with all the usual radios: WiFi, Bluetooth 4.0, NFC, A-GPS and even GLONASS. According to an ASUS rep, the device uses a nano-SIM rather than micro-SIM. Around back, ASUS has added a 13-megapixel autofocusing camera with an LED flash, five-element, f/2.0 lens and burst shooting at eight fps. There's a front camera too, capped at 2MP, in case you want to do the occasional video chat. Meanwhile, a slightly bigger 2,400mAh battery promises up to 19 hours of 3G talk time, and up to 40 with the dock attached.

Like every other PadFone that's been released, this won't be available in the US, but the phone-and-dock combo will cost £799 / €999 when it goes on sale in Europe this April. The phone is also headed to Asia, though we don't have any more details. You'll also have your choice of colors, we hear: gray, gold and hot pink, if that's what you're into.
