Reason not to buy it... If Apple doesn't take it serious why should anyone do so?
BT 5.3 LE , WiFi 6 + WPA3 and probably other power saving LTE/5G/GPS technologies missing.
On top newer cores and TSMC N5/N4 vs N7 would help a lot to improve battery runtime...
Especially as the runtime already is a joke - won't by anything that is below 7-10 days so you can charge it once a week and be fine. What's the point of a smartwatch if you have to charge it every [second] day but being able to use it then?
Classic Apple milking Idiots - and no I am not generally against Apple and write this on an iPhone.
