As BlackBerry Storm 1 user, and other BB's before that one, the Data plan is not all that important as I pay it already to RIM via VZW. So that is not going to deter me from getting a Droid !
You want the best toys, ya gotta pay the price to use them. Such is the techie world !
Yup, that's the way of the smart phone. I too have a Storm 1 and am already used to the 30 a month, so if I switch to Droid it won't be a big deal. The data plan gives you unlimited data / email useage, it's definitely worth it. You could always switch and pay per MB for your data, but you'd go broke really fast, trust me.
