As much as I’m loving my natural titanium with brown leather loop, I’m going to return them.
I read that sleep tracking will be attached to the series 6 and won’t be a software update and that is just unacceptable anymore for me.
I think I’ve just had enough of Apple doing this and trying to blame the hardware instead.
Apple is better than most companies in providing software and feature support for older hardware so you'll be highly disappointed with practices from just about every other tech company.
Samsung provides, I believe, 2 major software updates before they expect those wanting new software to move to a new phone. Right now I'm still using an iPhone 6s Plus with the latest software. I don't expect Apple to update the 6s to iOS 14 next year but it has easily outlasted a Samsung.
Apple is in a lose-lose scenario because they could provide an always on display for the Series 4 watches but then people would complain that battery life was terrible and that Apple did it on purpose to try to get you to upgrade to a newer version. Or they could in the situation they are now in that they didn't provide it and some will be mad at Apple saying they used to same ploy to get you to upgrade.
Tear-downs of the watch has confirmed that there is new hardware in the Apple Watch for the always on display so there is no reason to think Apple is not telling the truth. And we are all aware of battery limitations and that energy from a battery is needed to keep the watch display on.
And there will undoubtedly be new hardware in future Apple Watches that will bring new features unavailable to previous versions. This is simply the progress of technology.
