Thanks for sharing. I also do mac development, and I have one app today + another in the pipeline. My current App, Maxel (http://maxelapp.com/) sells at a 8 bucks (for a download accelerator, pretty busy market), which I don't think I could pull that off on mobile.

Now that's just a utility. Business type apps can command $40+ if they're good, and the top sellers are often high-priced.
