I switched carriers from time to time, but I never looked at Verizon/Sprint network. Anyway, the AT&T coverage is not bad in the Seattle area. Typically, I use 2 to 3 gigs of data per month. Sorry if I clog up the network. It was pretty bad when I was in Vegas last year tho.
Yes, I will get an iPad when it's available. With all the Verizon's ad campaign, it makes me dislike them.
