That looks very cool. How much extra work would it be to produce a Microsoft Smartphone version? (From what I know, most of the APIs are pretty similar, but obviously there are a few look-and-feel changes due to the lack of a touchscreen.)
I'm trying to retire my old bloated Palmphone, and most likely I'll get something like a Cingular 2125 (or Audiovox SMT5600, or Motorola MPx220 -- they're all very similar). But I'd rather not have to write a whole CacheMate-alike for myself...
(I've looked at Java solutions like Spot, but most of these phones, despite having both Java and Bluetooth, don't have the glue code (JSR-82) to link them together and hence get the phone talking to a GPS blob. Plus Spot was pretty awful the time I tried it.)
