I do believe that’s the only hand that Muslms wash ... LOL ...
As for me, since I’m not a Muslim, I do wash both hands, and take a bath or shower ... :-) ... and ... I do intend to get one. But, it’s “on a list” right now and there’s some other Apple equipment coming first ... :-) ...
And my comments (regarding it looking like the Dick Tracy watch) hold for any ‘smartwatch’ (others are being discussed in this thread).
I thought of the water issue because I remember the problem with watches in the 70s and 80s if they weren’t waterproof (and you didn’t have to be a swimmer or diver to experience them).
People get caught out in the rain as well. Sucks when it happens but it is a not so rare occurrence.
Hopefully there is something in the design that deals with this.
