Sony\'s PS Vita has officially gone on sale in the UK, with some high street stores opening at midnight to allow gamers to get their eager, grasping mitts on the handheld console.While reports from Amazon.co.uk yesterday suggested that the Vita is in for a healthy launch among dedicated gamers, we\'ll have to wait and see if it can muster up enough mass appeal to prove a long-term success.
