The original reason I got TB was to tether to a new iPad 2. I wanted to get just the wi fi model. Then I was going to use Hotspot to connect data to the iPad2. Well, I haven't bought the iPad2 yet (because there aren't any to be had). After a week with TB I now believe I really don't need it. TB will get me all the net I want in a perfectly readable format. I may now wait for iPad3.
