I wonder if people would pay for a PIM on the 770/N800. I've been meaning to start a PIM project with a back end based on Google Calendar and GMail (for contacts); I just don't have the time, and without a C API for Google Data, it won't be easy. I'd quit my day job if I could make enough money writing a PIM for the 770/N800, but I don't think the market is big enough.

Maybe someday, though...
