I have the Logitech Ultrathin Keyboard Cover. It has the same sort of magnets as the SmartCover and is a very thin Bluetooth keyboard. (It's a bit thinner than my iPad 2.) The keyboard also acts as a stand as well as protecting the screen when it's closed. I didn't want a folio case with keyboard, as I want to carry other stuff with it. When I want less bulk, I use a SmartCover.
