The trouble for Windows RT started in 2012, but 2013 was the year every PC and tablet maker abandoned Microsoft’s gimped version of Windows 8 (now Windows 8.1). Now the only two remaining supporters are Microsoft and the company it acquired in Nokia. The Microsoft Surface 2 ($449) and the Lumia 2520 ($399) are actually quite compelling in terms of hardware, but the value proposition is way off. You can get the ASUS Transformer Book T100 running full Windows 8 — meaning you can run desktop apps in addition to Modern touch apps — for just $349 with keyboard included. Adding a keyboard to the above RT devices brings the total to $550 or more. Even cheap 8-inch Windows tablets now run the full OS, complete with Office preinstalled.
