I still love my Apple Watch, but mostly as an attractive piece of jewellery that tells the time. (I have the SS with Link strap.) In so far as I think it looks good and it's effective at telling the time, I'm happy. It is a watch, after all.
I have zero concerns about battery life. I'm totally used to the tiny lag between lifting my arm and seeing the clock face. I'm perfectly happy with its performance in this regard, and it stays on long enough, especially with the 70s option.
After endless months of faffing with various options, I've settled down to using the watch for: telling the time, for timing things, as a bedside clock, to check the temperature and to check the exercise rings. (Though these last two are pretty unimportant and I could live without them.) Apps are pretty much a non-starter: they're ridiculously slow and mostly pointless: I have my phone with me. On one of the clock faces I regularly use, I've started using the Calendar complication, though I've discovered that Calendar syncing is not reliable. I stopped it from giving me e-mail notifications as most of my e-mails are boring. I get iMessage and Facebook Messenger notifications, mostly because I can, rather than because I need to.
Someone posted (on this thread?) about the Tag Heuer Connected:

I think Tag have really missed a trick here. From the reviews, it seems like they've failed to make it a sufficiently luxurious product. The pixel density in particular is poor compared with the Apple Watch. But when the time comes to choose between the Apple Watch 2 and the Tag Heuer Connected 2, I'm making no promises that my two decades of brand loyalty to Apple will rule out the Tag. Whichever's prettiest wins.
Indeed, my brand loyalty to Apple in general has been challenged this year. (Though this might be because I've joined these forums and been influenced by the many complaints people make.) The Apple Watch release was not well managed. The iPad Pro release has been similarly poor (seriously: no Pencils?) Apple's oversights annoy me: split view on my iPad Air 2 is great, but I can't have two Safari windows open in split view. What? No-one at Apple thought of this? The new Apple TV is pretty good, but it's not yet a game changer. There's no iPlayer app yet. Why not? Don't say it's nothing to do with Apple: they've got an unimaginably large pile of cash lying idle -- why didn't they pay developers with must-have apps to have their apps ready on Day One?
All this being said, my MacBook Pro continues to do sterling work, day in, day out. (And unlike previous Apple laptops, I no longer worry about the battery running out. It never does.) Any my iPhone 6+ (especially now I've got rid of the cover and use it nude) is both a thing of great beauty and a fantastically useful piece of technology. My brand loyalty to computing and smartphones has no challenger. No-one's anywhere near Apple.
On the other hand, will I buy the iPhone 7? Probably. I'm addicted. But how much better can it be? The iPhone 6S, despite Apple's ridiculous hyperbole, is barely different from the 6. 3D touch? Really? I think they've run out of ways to make the iPhone better. It is already superb. Any further changes will be marginal at best.
