They do have their advantages though. The one thing I will miss about my Bluetooth PDA/Bluetooth GPS combination, when I switch to my wired PDA/eTrex solution, will be the ability to lift the PDA out of its docking cradle in the car and still use the GPS.

If my wife is driving it is very useful for me to be able to grab the PDA, make some changes to the routing and then pop it back in the cradle. I'll lose this ability when I dump my bluetooth GPS.

I won't however miss the awful combination of TomTom and the bluetooth stack on my PDA though...

P.S. the Fortuna adds insult to injury on the battery life from, it manages to run down its batteries even when plugged into the 12V power in the car
