The Apple Watch , I'm not too sure about this.

It looks great, it has many features and is supposedly extremely scratch resistant.

What are the things that are cool ?

1- You can answer a call through the watch - no need to pull your phone out of your pocket.
2- You can check, delete, move and mark your email.
3- If you get an email with a specific date you can automatically have that added to your calender.
4- it tracks your heart rate, has a pedometer, and has access to health related apps.

If the price and battery life are good I may consider looking into one as it is extremely customizable.
