A few highlights of Series 6, 7 & 8: 6 was the first to have a Blood Oxygen sensor and app. 7 had a new screen size & shape and a full keyboard. 8 has crash detection (and with watchOS 10, that same technology can be leveraged for sport-related applications via a new CoreMotion API).
@lorihc I just reset my series 7 while on the beta, the new tool tips for navigating watchOS 10 was awesome, I really enjoyed going thru that little tutorial
@lorihc S7/8 fast charging has been the best for sleep tracking 🤓
@lorihc Something I would *love* in a future watch or watchOS: auto pause & resume for outdoor walks. I love it when biking, but my knee forced me to stop being a runner and now I’m a walker for exercise.
