I'm starting to like the idea of wearable tech more but only if it can provide me with something extra or remove the need for an existing piece of tech. Telling the time adds nothing as it's a watch, that's the bare minimum. Being able to tell you that someone has sent you a text, for when the phone in your pocket is an inch out of reach?
I do like the heart monitor, pedometer , temperature features etc. There are devices that can do this but you don't need them if you have a decent smart watch.
I'd like to see some decent applications like the ability to replace credit / debit cards, ID passes, home and car keys. The security would have to be increased significantly for me to trust the provider of such a service with anything more than pictures of my dogs though.
