The Asus Padfone is a very good concept, though not without its shortcomings. The small battery inside the phone, for example. Its success may also get hampered by the price being asked for it. During MWC, I was told by an Asus rep that the price for the phone+tablet dock combo should be somewhere around £450 in the UK. And that's a decent price, even compared to other high-end Android smartphones. And you're basically getting two devices for the price of one.
However, £699.98 is anything but a good price for the Padfone. And unfortunately that's exactly how much one retailer, FlagshipFones, is asking for it.
