I really like the look of the app and I like the concept. I'm not sure I'd use it enough to make the monthly cost worth it when there's codecademy, khan academy, and many, many other sites where you can gain the same learning for free.

How about actually coding on the go? Has anybody ever tried to do semi-serious Ruby or Rails coding on an iPad?
