I wonder if in the near future we all just share phones like you would a phone booth. Have devices everywhere or the capability on any device or anything electronic since it will be all wireless and connected anyway. You'd sign in via bio-metrics or some way to securely and uniquely identify yourself quickly.
How much data is on your phone? How much sensitive data is on there? Do you really want to wait to download all that crap, and run the risk of picking up a public phone that’s been set up to clone it all somewhere?
