Watch gets a lot of hate, but the pebble is amazing. I can't wait until I get my pebble time steel.
I enjoy receiving notifications on my watch, instead of having to pull my phone out and start mashing buttons to see them. Quick flick of the wrist and I can see if it's something I need to look at in more detail like a text or if it's just a generic facebook thing. Incredibly useful at work where you're frowned upon for being on your phone all the time.
Mostly though I use it for controlling my music. Walking along, cycling, or even sitting at my desk at work, I can skip tracks and adjust volume etc via 1 press of my watch (when the app is open). So amazingly convenient.
As for people complaining about the price, saying it's too expensive, there is no cheaper version, and it's not bad really. Your average fashion piece will set you back 50-100 quid anyway without all the features.
And if the watch doesn't do something you want, stop complaining. Do you go onto amazon and review their cordless drills by saying 'this drill is way too expensive I don't even need a cordless drill, my corded drill can do everything I need, so this is overpriced and a joke'?
So why come on here and do it with the watch! If you don't give a crap about facebook and sms and email notifications, the product ain't for you so why criticize it. Fact of the matter is most people are super-connected to the internet and each other, we spend all day instant messaging, texting, facebooking, e-mailing etc. and it's become an intrinsic part of our lives. The watch enhances this connectivity and for that we praise it and get a lot of use out of it.
