Was planning on waiting for 3G version of iPad. For work, I have a MiFi card which will give the iPad 3G access regardless of iPad version. Question is, what will I be missing out on if I pull the trigger now and get WiFi version without the GPS component? I can't foresee using the turn-by-turn directions when driving due to the unit's size and, besides, I already have an iPhone. What current and future applications of GPS do any of you think would be nice to have on the iPad?
