The Perspectives are the major downside of having only the iPhone version. Custom perspectives are one of the best things in OF since they allow you to easily access exactly the information you need with just one click.

However, I think Allen had no perspectives. There are a few built in into the iPhone and to get started you should be fine. It depends a bit on how many complex projects you will be using. Same goes for the review process. May I ask what profession you will use air with?
