I bought one the day it came out, it was fun to play with for a month or two and it's been in a drawer ever since. It just doesn't do enough that's useful to me, and it's uncomfortable to wear. The only Apple product I've ever had that I didn't love.
I use a Fitbit Alta as my every day watch. It counts steps and miles, it gives me calendar, text and phone notifications, the fitness app is way better than Apple's, and it's lightweight and unobtrusive.
If you do decide to get one, make sure you look at the apps available for it. A lot of companies have dropped their Apple Watch apps, or are planning to in the near future.
