Well since there are a ton of apps, I think it depends on what do you plan to use your iPad for, like gaming, working, studying purposes or all of the above. Since it's your first iDevice I recommend you getting the "app start" app by appadvice. It can be very helpful and teach you a lot of things about the iPad and the app store, that I would call a "MUST" for newcomers
Oh, and welcome to the apple world!!
