The new BlackBerry KEYone won't be everyone's cup of tea. If you remember physical keyboards with a certain fondness, however, then the KEYone offers the latest version of Android, a respectable camera and the kind of battery life you want in a productivity machine. After launching exclusively at Selfridges last week, the KEYone goes on general sale in the UK today, not that you need to look much further than Carphone Warehouse, which is the only place selling the device on contact right now.
