Sony SmartWatch 2 Brings Android and NFC, No Sony Phone Required. There is no question that the only functional SmartWatch out there is the first version of the Sony. Now, with a bigger screen and NFC, the next version promises to be even more functional. While I can read text messages on mine, you can't really read emails, and some of the cooler apps, like camera view and camera click, will be much better on a larger screen. I will definitely be watching for this one.
