I think a lot of people overlooked a specific keyboard.
If you're will to go with the apple wireless keyboard and incase origami keyboard case, I say save some money and get the Logitech Tablet keyboard for iPad. The keyboard is a full sized keyboard and it has all the iPad shortcut keys that the apple wireless keyboard doesn't har. It also comes with its own case which doubles as a stand for the iPad. This keyboard is a lot better than the one apple makes.
