The second, and probably most useful of the three, is a keyboard dock. This gives a full QWERTY keyboard for touch typing while charging the iPad and will let users thump out long documents without having to rely on the virtual onscreen keypad.
The last one is a carrying case that can be folded to let the iPad stand on a table for watching videos.
If there's one thing you can be sure about Apple products, it's that there will be a flood of third-party accessories very soon. One of the things we hope to see soon is a foldable portable keyboard like the Stowaway model popular during Palm's heyday.
