I'm thinking about getting one of these. I like the fact that it's not device specific so I can just use it with whatever I device I need to carry that day. The only drawback is battery life from what I can tell. I'm thinking more for out of town travel than daily needs. Has anyone tried both? Looking for the pros and cons of each. Sprint has faster speed, they do have 4g where I am now. And they seem to have a better fee structure. I don't like verizon's data limits. I haven't been able to find out if I pay full price if I can get it without a contract and turn it on and off at will as needed.
