Based on your points:<p>a: Agreed with the medical uses, but I personally, don't wear my watch that tight. Maybe I would if it had value, but my watch is closer around my wrist bone and loose. Then again, it's a metal band and not leather / plastic, so it's usually either too tight or loose.<p>b: I have no interest at all in controlling my TV by flailing my arms. Thats just not me.<p>c: yes - but not by movement. Volume buttons that can double as up down arrows or something like that (but then, why wouldn't you just swipe the screen of the watch) to navigate would be cool. I don't see an iWatch having a lot of buttons, if any.<p>I've had many discussions about this with many people; from salesmen to doctors.<p>My personal hopes for the watch:
Be good at what it should do: notifications. Show me what music is playing; what the caller id of the incoming calls is; who the text message is from; upcoming appointments, etc... And just like the iPhone, it's top priority is to show... the time! A watch is still a watch and if its gonna replace my Tagg Heuer, it better tell the damn time.<p>I also think though that a problem with these devices (including Google Glass) is people that wear expensive sunglasses, expensive watches, etc... do so, mostly because of style. I think Google should partner with a Ray-Ban, an Oakley or whoever to make the frames for them. I highly doubt Apple would, but it would make sense to hire a Tagg, a Movado, a Tissot, etc... to make the bands / face casings. I've joked that if Apple made a watch, I'd wear the Apple watch on my right arm and continue to wear my Tagg on my left. A watch still very much has value to me, even though my phone is always on me.<p>More than anything, I want an iWatch to stop me from looking at my phone every 5 minutes. The action has become obsessive and I can't help but think it's rude. Looking at your watch constantly says to people your in a hurry or in a rush. Looking at your phone all the time tells people your a socio path or don't care whats happening. Neither are good, but the prior is less of an evil then that latter, haha.
