I don't really know much about tablets, but my parents have decided I need one for school and have offered to buy me one, as long as it's under $500. Sweet! I'm not complaining, so does anyone have any recommendations? I'd need it for drawing, but I would also like to be able to do other things on it as well like view powerpoint presentations or browse the web. Are those features possible together? If not then forget the drawing aspect, I can manage with just paper and pencil.
