Yes, but if you want to focus on sports you can check out garmin too. I have an AW and a Garmin Fenix and while the apple watch is a great smartwatch (=best smartwatch i would say) and it can track all sports too the garmin watches track more detailled metrics when doing sports or also while wearing it to work or wahtever. But garmi watches are not really smartwatches like apple watches are. I have both and they both have their advantages.

yes

My mother didn’t really pay a lot of attention to her macbook and it stills works after 9 years (i think).
