I haven't yet run across a website yet where Flash doesn't work. You'd better list your "problem" websites, otherwise everyone will assume you're speaking in hyperbole and blowing stuff out of proportion as a troll. If there are technical issues with specific sites in IE, bring it up with Microsoft on their official boards.
Your entire post, like I said, really missed the point of Surface/Windows RT. ARM was chosen for battery life, and regular Windows doesn't run on ARM, so MS had to make another version. Can and should Mac OSX run on the ARM chip in an iPad? If you answered "yes," I suppose that illustrates your incompetence. You keep talking about the Surface RT line as missing this and that, but the reason why you're completely wrong is because you're comparing it to a Windows 8 machine. Thus you're passing off your bad consumer choice--yes, a character defect on your part--as the fault of the product, all stop. But guess what? When compared to its proper class of mobile OSes, Windows RT can do a lot more than iOS or Android.
Now, if you said you were elderly and weren't technically savvy at all and a salesperson duped you into buying it at the store, I'd feel more sympathy for your plight.
