I agree that the iPhone comes close to succesfully combining multiple technologies into one device. The next step is having a similar device that is wearable, out of the way and intuitive. If you can wear it like a watch, then you are good to go!

Free time.

Smart phones exist so we can get more work done, so why don’t we get that time back? Instead, we use them to work while we are eating meals, driving cars, or missing family time. Productivity/efficiency devices should give us more free time.

I’d like to see a feature on phones that will break in on either your voice or text sessions to tell you that you are currently ignoring all of the people that you’re standing with that are tired of your conversations being interrupted by your phone/communicatoins devices. I don’t know why some people bother physically going to any place to be with other people only to spend the entire time on the phone with other people.
