Probably the closest option to M1 on build quality and battery will be the AMD version of the Framework laptop... if you want can run Windows or Linux without issue. Will probably go that direction on my next purchase. Later this year and next year AMD are releasing new laptop CPU/APU that will absolutely kill on performance:watt, while they're a bit ahead of Intel at the moment, they're going to leap a bit further ahead if GPU perf matters to you. Not that Intel is asleep, just behind.

On the phone, I started with Android, so just kind of used to it... I've bought about every 2-3 generations for a while, currently on a Pixel 4a. I tend to avoid the high end, and find if you wait 3 months or so after a new release, the kinks are usually worked out by then.

As to the iPad, there really isn't a good alternative that I'm aware of... there are still a few Android options, none are great... the MS surface tablet and other convertable laptops are okay, but still not as nice a UX, it's not my thing so doesn't bother me, but can understand why if it works, it really works for you.

Watch is about on par, from what I understand.. again, not something I'm into personally.

I tend to take the Apple option for work (software dev, mostly web/svc oriented) only because corp Apple experience is generally better than corp windows.
