This is the Asus Padfone that just got officially introduced at Computex 2011. A package consisting of an 4-inch Android smartphone which can dock into a companion 10.1-inch 1280 x 800 tablet. The tablets separate battery can be used to recharge the phone, while the phones 3G connection can get the slate online when away from a WiFi hotspot. You can see additional photos, here. ASUS is promising a seamless transition from the phone to the tablet UI, with whatever youve been looking at on the handset automatically expanding to suit the slate, along with the improved web browsing experience youd expect from a bigger display. If a call comes in while the phone is docked, then it can either be removed or answered with a Bluetooth headset. Phone and slate can access the same storage in the handset, and since theres only one 3G radio then you dont have to swap your SIM between two modems (or sign up for a second data agreement). The UI has been modified to suit both displays, either showing mobile sites on the phone or full sites on the tablet. The phone itself has two cameras, a front-facing webcam just like the tablet itself and a 5-megapixel camera on the back which can also be used through a hole in the PadFone dock. ASUS is saying that finalized hardware specifications havent been decided on yet, and nor have pricing or availability, so dont get your hopes up too much. Still, as concepts go, this is an intriguing one.
