The most wanted feature is to have a display that shows information all the time at least for health apps or similar.
Current Apple Watch compared to a standard watch:
Watch displays time/date all the time (perhaps not in the darkness). Very easy to look, you don't have to raise or twist your arm.
Apple Watch requires a very awkward twist of your arm (not always working, not sensitive enough) or raising your arm to make it display info. In many cases you also have to wait a while before data is updated and valid.
Fitness apps for running. Awkward to use, haven't found one single app yet that is good enough. If compared to e.g. a Garmin Forerunner:
- Garmin shows info on the screen all the time. No twisting or lifting your arm.
- Garmin shows updated info all the time, no waiting.
- Garmin is stand alone, with GPS, Apple Watch requires an iPhone and the connection between them is not always reliable.
I understand that battery power needs to be saved but I can accept it being drained on a one hour run if it just can show updated info all the time. I can put it on charge when I'm in the shower afterwards.
For showing time, it can have some part of the screen that is visible all the time, like e-ink. Time should be shown all the time.
I can accept that the iPhone is required for GPS data but I can't accept the slow response from the screen when I want to look at current information when running etc.
