from the way you've phrased that question, I take it you need a Windows based tablet, not an Android one?
If so, hang off buying anything for a few months. Most of the normal "big players" in the PC market are holding back on releasing a full range of windows tablets while they wait for Microsoft to make a move: M$ are threatening to release their own hardware in competition with the usual suppliers and its very uncertain just what is going to happen.The big boys are very very pissed at present. You may find windows tablets die (another) death. You may find in a few months that the range available suddenly explodes......
Don't forget that before Windows 8 M$ had at least two abortive failures with "tablets" - who remembers XP tablet edition? (I still have a setup disk for that somewhere.....) and the attempt at a Vista tablet
