The ExpoDev software does look very functional, especially for large-format photographers. Folks reading this thread might want to check it out at ExpoDevPalm, along with the companion Plotter software.

However, the developers of the software don't seem to be very Mac friendly: only Outlook synchronization is mentioned, and Plotter doesn't run on a Mac without emulation software. This, along with ExpoDev's $100 price tag, limits the appeal for me. I wonder whether BZTS is looking into creating an iPhone version of ExpoDev?
