Awesome. Thanks for that. I spent way too much money on boardgames a couple years ago after discovering boardgamegeek but I always thought board games on a mobile device would be cool.My wife and I have been playing to death the port of the boardgame Smallworld to the iPad. It's a wonderful implementation of a boardgame and I look forward to many more games like this.
Over at boardgamegeek.com they have a growing list of boardgame ports for the iPad.
I just picked up Smallworld, after reading your post. I also noticed some Reiner Knizia games are on the AppStore but just for the iPhone.
The iPad is a perfect device for board games. I hear that Catan is coming soon to the iPad too and also Carcassonne.
