Hands-on review: MWC 2013: Asus Padfone Infinity

So this is it: Asus' latest and greatest Padfone. Far from being the joke the concept was initially seen as, Asus is serious about its tablet and accompanying slot-in phone and has re-tooled it for 4G LTE, Android 4.2 and provided it with a cracking Full HD display.Indeed, display tech is a key new ingredient in the Infinity mix â€" the phone part boasts a Super IPS 5-inch retina-beating display at 441ppi which, while looks stunning, doesn't appear that much better than any other top end Android handset (hello, Samsung Galaxy S3). The iPhone's retina display is 326ppi, if you want to know the figures. As with the Padfone 2 (which is coming to more countries including the UK), the slide in and out motion works exceedingly well both in terms of the physical movement â€" it's completely secure and rubber gromits mean the phone doesn't fall out â€" and the software, which switches from one screen to the other when you dock and un-dock. The Infinity was announced by Asus' Jonny Shih on stage at MWC 2013, where he was joined by Qualcomm's Paul Jacobs â€" the new device packs a 1.7GHz quad-core Snapdragon 600 CPU and uses the US firm's third-generation LTE tech. This thing is fast; there's absolutely no lag but then you'd expect that with a quad-core chip. Asus reckons it's possible to get 19 hours of 3G talk time out of the device when it's all fully charged. The Padfone Station dock converts the phone into a 10.1-inch tablet with 1,920 x 1,200 r
