I guess if I have to ask how much it cost per month I can't afford it. True?
That all depends. I pay about $70/month. The unlimited web package is $30/month and voice is another $40/month.
Soon Verizon will be allowing Skype over their network so, theoretically, one could make all calls via Skype. There are already some Skype apps on the Droid that make this possible so one could go with the data only plan.
I neglected to mention one of the other selling features that made me choose the Droid. It was only $99 with a 2 year activation and I had recently won a $250 gift card at a banquet. For the iPhone with 16gb it would have cost me close to $200 for the same memory.
