Microsoft Surface RT, £399, (32GB)
Microsoft may be late to the party, but at least it's turned up with something a bit different. Constructed from "VaporMg" magnesium alloy the Surface is a solid looking tablet that comes with a retractable kickstand and optional protective covers (£65-£99) that double up as keyboards. Running Windows RT - the mobile-specific version of Windows 8 - the Surface is unable to run regular Windows desktop software, though you do get the Microsoft Office suite pre-installed. Connectivity extends to Micro USB and Micro HDMI inputs, although sadly there's no direct SD card input. Screen resolution is a rather low 148ppi too.
OS: Windows RT
Screen Size/Aspect: 10.6in, 16:9
Resolution: 1366 x 768 pixels (148ppi)
Pros: Good for productivity
Cons: Screen resolution is not the highest
