So... I've been thinking about getting a tablet! My budget is under $500, and the only things I really know right now are that I want it to have a screen. XD I'd love to get some opinions from folks that have used them, and some ups and downs of them. (The only type of tablet I've ever used was a $30 one from Best Buy. It was by Bamboo, and died quickly. The second one I got as a replacement died just as quickly, just quit working... so I don't have a clue.) ALSO what accessories are recommended?
