It is better because:
a) It has dead reckoning (this is a huge benefit over PDA)
b) It is all combined into one unit for total portability
c) It has a sunlight readable display so you can actually see where you are going
d) The volume is loud enough for you to hear without an external speaker
e) The routing options are far more sophisticated including POi's on route and multiple destinations.
A.As far as I understand it Dead reckoning is down to the gps device used so partner a better gps device with PDA.
b.My pda can either use the gps plugged into the CF socket at the top and can be used as a handeheld unit or I can use it as a mouse on a separate cable http://www.pocketgps.co.uk/haicom303mmf.php
same as this, i do this all the time and it is very good.
c. Ipaq's are renouned for there sunlight readable displays, some pdas are poor yes but then it is down to choice. choose an Ipaq and the display in sunlight is exemplary.
d. the volume is only a problem on certain pdas IE the ipaq 5500 and mitac mios 90% of them do not need an external speaker.
As I understood it a garmin streetpilot can show a POI but in terms of speed cameras can it give an audible warning a set time before you hit the speedcamera? where is there a database of speedcameras available that works with a streetpilot?
