For Wacom tablets that have the necessary WinTab drivers for pressure sensitivity, you're looking at the Samsung ATIV 700T and Microsoft Surface Pro for current generation Windows 8 tablets/convertibles/hybrids. We have reviews of these three on our site. The older Samsung Series 7 Slate (an Intel Core i5 tablet you can use with an optional Bluetooth keyboard) is another option if you're looking to save money since it's a 2012 Windows 7 model. We have a review of that as well, and I've owned one for over a year.
