Are you taking advantage of the iTunes Apps Store?

I recently found a post by Ben Lorica which looked into the best selling apps at the iTunes store. According to his post, the top sellers are apps dealing with sports, education and entertainment. Read his analysis.

After having a chance to browse the iTunes Apps store, I found a few companies who have already started to use it to their advantage. Slate has a Poll Tracker '08. ESPN has a few apps as well. What could something like this do for your company? Have you seen a great example of companies taking advantage of the iTunes Apps Store?
