A lot of GPSs these days have Bluetooth and so practically all PDAs and
almost all notebooks - now all we need is for the radio manufacturers to
include it.

AFAIK, there aren't any simple "microcontroller to Bluetooth" interfaces
available either. I forget the exact chip, but I'm fairly certain the
TinyTrak 3 uses some little 8 bit microcontroller with probably no more than
"many kilobytes" of flash ROM and "a handful of kilobytes" of RAM. That's
nowhere near enough to support Bluetooth.

Bluetooth is also a lot more power hungry than a wired connection would be,
and of course is prone to interference since it's operating in the 2.4GHz ISM
bands.
