I find that I use my iPad more and more recently. Lets just hypothetically speaking that an iPad mini has a retina screen (inevitable). Would you be able to replace a phone with an iPad mini with say, unlimited data (which I have), or even a 5gb plan? What would you use in conjunction with iMessage? I have never explored google voice but I'm assuming that's an option. What about calling? I don't talk on the phone much but that's definitely an option. I can see with the right device the tablet will someday merge with the phone, what do you guys think it will take for this to happen?
