Apple announced official development APIs for GPS location awareness and mapping yesterday so it won't be long before there's a dozen SatMap clones on the AppStore for your iPhone if SatMap don't get there first. In-application purchasing was added too so you could buy the app then buy individual routes too.

There's too many buttons on the Active-10 for the Jobsian Hordes.

I imagine there's at least a dozen developers that downloaded the SDK this morning and will have prototypes out by the end of the week. I did.
