its capable of being used independently of the iPhone. I know I'll get flamed for this but it needs to be said. I sold my Watch after 2 days after paying over retail for it on Craigslist. Its so dependent on the iPhone for everything, even native apps. Things like not being able to read most my emails and being told to read it on my iPhone was ridiculous. The Watch wont become a really useful device until it can be used in a pinch when you forgot your phone in your car and you're in the grocery store, or you leave it at home and you have to get somewhere and don't have time to turn around. Having to have your iPhone with you really defeats the purpose IMO. Who's this really benefiting aside from people just looking for a new toy to show off?
