Hardvare platform for GPS devices?

Hi!

Colud you please explain me briefly wich is most commonly used hardware
platform for GPS devices today...For example, hendheld devices? Which
procesor type, speed, ammount of RAM etc....
If you have some GPS devices hardware specifications please send link or
something...

I would also like to know which is commonly used operation system for those
devices? Some kind of Windows CE, Simbian, Embeded linux, or something
else???

Thanx in advance!

For a pocket pc take a look at the Dell X51(www.dell.com) or the the HP
IPAQ hx2495(ww.hp.com),
processor speed and memory is no problem with either unit. You will
probably need a 4 gig SD(150X) card
Transcend or Sandisk. A bluetooth gps receiver and make sure it has
SIRF III or compatable chipset.
For information on these gps receivers go to www.gpspassion.com.
For Street Level Mapping software take look at IGuidance. For GPS
mapping software take a look at OziCE
and OziExplorer at www.oziexplorer.com. (Windows)
A good program to help setup a blutooth gps receiver is Franson GPS
