Thanks to the help of a kind Mastodon acquaintance, I've upgraded my Series 4 Apple Watch to a Series 10 and wow it's a lot nicer. Feels slimmer and lighter, has a bigger and brighter screen, and is *so* much faster. Plus the battery should now easily last the whole day again!
Maybe the lesson is to upgrade tech less often because then when you finally do, the small incremental changes add up and feel like a huge leap. ๐
