I very recently bought the previous SE on sale and with additional discounts for just under £150 and I'm glad I went for it because I don't the upgrades to the newer SE (now £270 here in the UK) or even the previous S7 on sale would have justified the additional expense (although I do slight regret not having the bigger screen -- oh well). At this point I'm just waiting for massively better battery life or another change in utility to really justify an upgrade.
I'd been resisting an AW for a long time and mainly wanted to try it out. So far the experience is pretty, I don't know, underwhelming for anything other than fitness and health tracking. I wasn't expecting too much, to be honest, but I find the actual smart features of the watch not as useful as I was hoping. The navigation on public transport and inner-city walking is quite nifty and definitely useful, but other than that I felt the watch faces and complications too limited, too few and too static. For example, why can't the AW dynamically adjust the information it presents anywhere other than the Siri watch face, which is absolutely hideous.
Anyway, it's a nice new toy but I'm not yet convinced I will actually use it long-term or just go back to trusted analogue watches and just use the phone for all the content.
EDIT: I generally think the next big upgrades for the AW must be a significantly better battery life at the normal form factor, but other than that I think it needs software rather than hardware improvements -- generally driven by a clear vision what the watch should actually do. Other than be a fitness and health companion I just don't see it right now.
The watch is exactly for that, motivate to go start sporting or log your activities if you already sporting.
But i agree i wish the AW gets a boost in artificial intelligence that keeps all data on the watch only but learns you and helps you by coaching tailored made excersizes, coping with stress, or other health related potential/issues you may develop or have.
There is so much more that can be done on the software side alone without the requirement of additional sensors etc, but Apple is extremely lackluster on this department unfortunately, so it remains a fitness recording watch and acts as a terminal for your phone for notifications etc unless you use LTE.
Which in my opinion makes the AW more as it suppose to be a standalone device.
But the truth is most people using the AW are not the frequent sporting types, the use the AW as a external display for their iphone to show messages etc and then the device experience is super lackluster.
It really must become a personal health/organiser coach instead of a device with pre-loaded metrics that it will measure once you start a exercise.
Examples:
AW tells you to stand up every hour, why not make it smart and gives you a goal to walk, it knows your location, it knows your rings, your goals etc, why not tell you to walk 100 meters or something like that, to get the blood flowing etc.
Why Fitness+ is behind a paywall, why not part of the product, give us tailored training based on age, weight and all other metrics you fill out in the health app, tailored to give you a training schedule to slowely become healthier/more cardio including stretch/rest days etc.
Make the AW make actual use of the GPS location, it knows where you are, why not make it smart to detect you are either doing a daily commute to work, or walk your dog in the same park etc etc etc.
The software is still so super lackluster. I do believe 10 AW versions from now will actually have a lot smarter ways to track our behaviours etc for personal gain.
