I use my Ipad for Reading e-books, as a photograph viewer for my Nikon D700, emails, facebook on the move, and many more little things, and a portable games machine for my son.
Good to hear from you. You'll find this Forum the absolute best place to find out all you ever wanted to know about your iPad - and probably a load of stuff you didn't want to know too!! It's full of really friendly guys who are just crazy about the iPad and are more than happy to help other enthusiasts. Don't be afraid to ask *any* question or use the Search button near the top of the Forum page (it's so obvious that everyone misses it!).
