Right now I am in the 700 minute family plan with unlimited data and texts (around $160 after all taxes and fees). I use around 3gb per month on 3g. My upgrade is not until 7/20, so I will try to get an early upgrade, but from reading online it does not seem likely. Looks like I am going to be moving backwards rather than forward. I bought a 64gb card to use instead of Cloud. I will most likely buy a GPS instead of using one built into the phone. At that point I might as well get a dumb phone and a wifi tablet (nexus 7 maybe).
I could see this being good for a large family, but right now, I am tempted to pick up a Google Nexus from the Play store and try t-mobiles $30 unlimited data, text, and 100 minute plan (just use my landline more, which I pay for in a triple play package since it is cheaper, even though I never use it).
