To Tablet Or Not

So, I'm considering getting a tablet for general internet use and for my art. (I'd like something to take out with me so I can get out a stylus when I'm feeling inspired.) I've been looking at the Microsoft Surface RT or the Samsung Galaxy Tab 2. Now, the reason I'm umming and ahh-ing is because one runs Windows 8 and is 32gb and the other is Android and is only 16gb. (Though, the Microsoft Surface is actually a 16gb one after you take into account the space taken up by the Windows software etc.) The Microsoft one has a 10.6" screen and the Samsung has a 10.1".

What I'd like to know is which would be better. I'm not really familliar with Android apps for drawing and such, but I'll be at home on a Windows OS and have access to decent software for it. Are the screens OK for such use? Do either come with pressure sensitivity drivers, or can I at least install them if need be? (I know with a Surface Pro you can. But, I'm not made of money. :P)

If you have any other recommendations, feel free to say. Though my budget doesn't stretch too far, so don't go suggesting something that costs £600+.
