The hotspot ability (I was guessing it was Verizon that had it based on AT&T's draconian practices that I've seen) and the larger data plan available was why I ordered the Verizon one also.

Edit: On that note, which GPS Turn-By-Turn app would you folks vote as the best? Since I never used a GPS before (OnStar works great for my car) I really don't know which one would be the best (a lifetime Maps/Traffic subscription would be great, but probably unrealistic).
