I will be buying an iPad 2, my first iPad. I have WiFi connections out the ying-yang and when I don't, like in a moving car, I will hotspot to pick up 3G. I know that one needs 3G for good and reliable GPS, but beyond that, what, if any, are the advantages of getting an iPad with 3G? And I understand that one does not need a data plan to be able to use the GPS (correct?)
For example, are there some really good apps that use GPS?
Thanks for any help.
