Re: Reasons to be Wear-y
I too have a SmartWatch 3.0 and was disappointed Wear 2.0 wasn't coming to it, but with the change in the left swipe, that sounds awful, and maybe I was lucky!
I got mine new from Amazon about 18 months ago, and I'd be lost without it. As you say battery life is fine (I had a mi band, that charged every 30 days, but I'd lose the proprietary charger), these things need to last months/years, or daily isn't an issue.
I use it mainly for notifications and deleting junk email. I can reply to messages quickly. It stops me getting my phone out. Also helps me locate phone in the house when I've put it down and can't find it. I add notes, and reminders with voice with it (live alone, so it not that weird). Pause, skip and ff music though it (casted, etc). I run, and although the SM3.0 has a GPS built in, I use a proper garmin for that (though have used apps when I've miss placed my garmin or it wasn't charged, I prefer buttons I can press when sweating to start/stop/lap, etc).
No it's not essential, and these £300+ devices, not a chance I'd buy one of them, but for the £80 or so I spent, I'm very happy and use it all the time, and would be a little lost without it... I would spend that again if and when this one dies though.
