One of the problems with the Wi-Fi-only iPad versus the upcoming 3G-embedded model is that it lacks A-GPS, a system that combines satellite data with cell-tower triangulation to pinpoint your location, even when you're indoors. That said, the Wi-Fi-only version can still attempt to find where you are using nearby Wi-Fi signals, and I was impressed when my new iPad immediately zeroed in on my apartment, within half a block. Not bad.
