Having looked at my usage for the last 12 months, I have to have unlimited options. If Verizon ever takes away 'unlimited' options, I'll stop buying smartphones.

As far as tablets are concerned, I know I'm sticking with Wi-fi as long as possible -- especially if we can get them to work with PdaNet. Who needs yet another damn monthly bill?
I think CNET's Molly Wood brought up a great point about how we're paying time and time again for the same damn data. I wish the carriers would just sell us data access on whatever freakin' devices - or as many as - we decide to use.
Once there is no longer unlimited data, this will be possible.
UNlimited data is the number one thing preventing data agnostic plans
