Microsoft's LTE-equipped Surface 2 has only been available in limited markets since it was formally announced, but today the company has said it's opening pre-orders in the UK. As per the company's usual sales approach, the 4G tablet is already live on the Microsoft Store for £539, with shipments making their way to doorsteps by May 8th. From that date, Microsoft says customers can also pick up the Surface 2 (4G) from a number of high-street retailers, including Dixons, complete with 200GB of free OneDrive storage for two years and a year of unlimited Skype WiFi calling and landline calls.
