I went there in April 2012. Computers are OK, and while the border guards check your luggage and take your phone (you'll get it back when leaving) they are incompetent; I brought an iPad and a camera with GPS. The camera even said "GPS" on it, and the guard noticed. But I acted confused and he let me have it back.
You're right about not wanting to support the government there, but the tourism industry is quite insignificant and not a major source of income for the regime. Do consider the moral implications of being used for internal propaganda, though. You'll be photographed wherever you go, and smiling is not really optional.
