Gaming addons for tablets

Here's an interesting idea: a joystick you can add on to your iPad for better game controls. It's $25, so you have to be willing to spend more than the cost of several games to buy one... but it is interesting, if it works as well as they describe. I don't think it will catch on in a big way, but it does show that gaming on tablets is enough of a market to encourage add-ons.

If only you could download it...
