Yeah, that makes quite a diff w/ & w/o it's own 3G.
I got the LG *** Watch as soon as it was out. When I first took it out of the box, I said, "Oh man, I don't know if I can handle something so bulky on my wrist." However, I haven't worn a watch since I had a calculator watch in elementary school, so the feeling would already be awkward with any watch. Based on pictures and video at the time, I feared the 360 would be even bigger, but it's definitely a nicer looking design. The initial reviews of the 360 were poor on battery life, but an update has since improved that. I do like some of Samsung's devices. What I fear most with them is that they pump out so many models, that they can easily move on and leave yours in the dust. I'd trust Moto, at this point, to provide updates a bit further along. It's too early at this point for me to assume watches will get replaced & forgotten as frequently as phones.
Generally speaking of smartwatches -
I still feel it's a completely optional piece of tech gear, but I do love the convenience of it. I personally hate ringtones and all the notifications going on throughout the day, either too loud or missing something from being too quiet. It's harder to miss a notification buzzing on my wrist, and it's easy to swipe away something that you would've been crashing your car trying to dig out of your jeans. I've actually had some meals where I didn't pull my phone out like everyone else at the table because I knew I wasn't missing anything.
Need more justifications? I almost bought a fitbit as everyone at work seems to have one. Consider that $99 toward the watch.
PLUS, you can check the time on your wrist! It's a novel concept, I know. When I got a phone, I said, "Why have a watch when I can just check my phone?" Now I say, "Why pull out my phone when I can just check my wrist?" I guess the watch just needed all other notifications to win me over.
If I weren't such a guinea pig for new tech, I'd wait for them to be slimmer and more refined. I know they all vary to a certain extent, but mine lasts 1.5-2 days with the screen always on, or maybe 3 days if the screen's off when not viewing. I just charge it nightly w/ the phone. Sorry for the novel, only to have no experience with either watch you're looking at. I do know the OS itself is unaltered between the 3 though, so the general info applies. I think with these for now, it's almost all based on preference of looks and comfort as the specs are very similar.
