Jeffrey P Shell loves Omni Focus. Second only to the ITunes Remote, Omni Focus for IPhone is the coolest mobile application I've seen so far on this young platform. Omni Focus for iPhone (or iPod Touch) can synchronize over WiFi, Edge, or 3G. That alone makes it very useful. Cooler still is that it's [Location Aware] (Location Based Service). "GTD" has a strong concept of contexts. A project may require picking up supplies at an office supply store, assembling at home, and mailing out items at the post office. With Omni Focus, you can add location information to any context. This location information may be based on where you currently stand (using Location Services), on a manually entered address, on an address from a Contact record, or on a business search. Then when looking at the "By Location" screen in Omni Focus, available actions get grouped by their location in relation to where you currently stand. "Grocery Store: 1 Mile; Post Office: 3 Miles..." Very Cool.
