Unlike some of the other Windows-based tablets we've tested, the Lenovo ThinkPad Tablet 2 comes with the full, non-RT version of Microsoft's latest operating system (AKA Windows 8 Pro). This makes it better suited to business users and people who require a fully-fledged mobile PC. Other chief specifications include an Intel Atom Z2760 processor (1.8GHz), up to 2GB memory and a 64GB SSD. It also comes with a Micro SD memory card slot for additional storage and a SIM card slot; something that many of its rivals lack.
