At most it takes me 2 seconds to take my phone out and unlock it to see a notification or read an email.
Well, goodie for you!

No, you really don't understand the watch. It takes two seconds for you to take out your phone. But it often took me longer. I wasn't always able to keep it in a front pocket. So into the purse it went. And there were so many times when I didn't feel it vibrate or ring with a message. Didn't hear the phone call, or if I did, thought it was someone else's phone. And I missed calls. I missed notifications. I missed texts. Sometimes important, even urgent ones.
There were also times when I heard the phone ring, and couldn't get the phone out quick enough and missed calls.
Now I don't. I feel taps and look, and there's reminders, texts, notifications. And phone calls! My friends and relatives are delighted; I'm responding and doing so promptly. Oh, and I also had a problem where I dropped the phone. I've got butter-fingers--things just slip away from me and my phone was constantly dropping. No dropping the watch.
Yes, everything I do on the watch I could do on the phone. But flat out, I do all those things more often on the watch, because it's right there to catch my attention. Like setting a timer. Could do that on the phone, but I kept my phone in my purse...so it never got used for a timer. The watch does, frequently. Also use it as a caculator, to pay for things, etc. It's right there...but unlike people who have their phone out and right there, I'm not always staring at it, texting or checking on tweets.
So far as I'm concerned, I get the best of both worlds in the watch. It's right there for me to use like the phone, but it's not there to also distract me like the phone. That's why I love it and why I'm very glad I got it. It's not for everyone, but that's fine, too. We have all these options so we can all find what is best for us. This is best for me.
