Like many of us, I have a smart phone (Verizon DroidX) that I can use as a portable WiFi hot spot. If I was going to get a 3G IPad with "use as you go service", wouldn't it make more sense to go with the ATT IPad so I have the option of using both ATT & Verizon service? I'm I missing something? I only plan to use the 3G when out of town or on vacation.
