Re: Watch 6 in September
I won't be getting one myself, but I'd love to see a redesign - something completely fresh. Maybe one with a protective bezel, to help prevent some display fractures. Maybe a move toward the use of simple Qi charging rather than the charging puck. Always better battery life. Maybe any extra button, so that there can be hardware button functionality for things like workouts, stopwatch, etc.
The rest of my wishes are probably more watchOS 7 wishes than Series 6 wishes. (Better AOD support for third party apps and watch faces; third party watch face support; more health sensors, such as blood oxygen levels and perhaps blood sugar levels, if possible; better workout support, especially running intervals, and make the dumb countdown optional already; iPhone independence, so a watch can stand alone, finally; support for syncing to iPad and Mac or even iPod Touch; Health data access on iCloud.com, MacOS, and iPadOS.) My watchOS wish list gets smaller all of the time, though.
