The other noticeable difference between the WiFi and 3G versions is that the 3G version has GPS too because the GPS functionality uses part of the electronics used by 3G.
So a 3G iPad will have full satellite navigation capability too. WiFi iPads have some capability in this direction by using a database of WiFi hotspot locations, which works reasonably well in urban areas but outside the range of WiFi, these iPads cannot retrieve the iPad's location.

Most likely for 3G gps triangulation. Who cares and need another gps if I have my 3G iPhone4 in pocket with same gps?
No, it has a genuine GPS chipset. You don't even need to be connected to any cell tower to use... nor do you need to even activate 3G to use the GPS functionality.The other noticeable difference between the WiFi and 3G versions is that the 3G version has GPS too because the GPS functionality uses part of the electronics used by 3G.

Thanks to apple locking down of the OS you can not just go buy any blue tooth GPS receiver and expect it to work with a Ipad. There are currently 3 external GPS units that will work with an Ipad and they all cost about $100.00 each
I bought the 3G version for the fact that it has GPS. I plan to mount it in my jeep and get a quality GPS app with topographic maps to use in the back country of Utah.
Cheap Garmin 100 times better? That is kinda out there, and not at all true.Gps is slow and not accurate in both iPhone or iPad, cheap garmin model could do job 100 times better.
