I use a Thinkpad T460s (Linux), 4 year old Android phone and an old Garmin running watch I bought off ebay.

The simple fact for me is that all of these types of devices are thoroughly comoditised now, and almost perfected, so even old tech runs well, for my needs at least. I don't experience any issues not being "up to date" and it feels satisfying to not have blown thousands trying to keep up.
