I agree that it'll be interesting to see what happen chooses. Ironically, I'm the exact opposite of your thoughts. I think the iPad needs to be thin to reduce the weight and usability of carrying around, traveling, holding, etc. On the other hand, while I wouldn't say the watch is the ideal thickness, it's acceptable (as you alluded to). In fact the watch I'm wearing right now is essentially the exact thickness, and holds extremely similar surface area dimensions as well (as close as a round watch can be, haha). Now sure, this watch is a super cheapy that I got from walmart 5 years ago, but that doesn't take away from the fact that I find this size/thickness absolutely acceptable. The weight on a watch will be negligible, so that's not an issue. The biggest issue with the Awatch going forward will be battery life. This is why I would rather see the Awatch stay the same size for a few generations untill they are able to get battery life up to at least 3 full days (for weekend travels). This is the minimum battery life (in my mind) before it's acceptable to start reducing the size.
I do wonder what Apple think about battery life.
I imagine they could very well feel there is no need for the watch to ever have a battery life better than the phone.
The watch is not a separate device. You need to use it along side your phone.
You recharge your phone every day, generally, so I can imagine they may feel, well, if you put your phone on charge every night, then you can just as easily put the watch on charge at the same time.
I can easily see Apple following this logic, and never seeing any need to have the watch able to last days, as what's the point as you are charging the phone anyway.
My view on watches, and, I have zero interest in fashion or what other people are wearing, or any need to show off anything I own.
I think my view stems from, when I grew up, men wore, what I would call classy watches. medium to slim, gold if they were lucky enough, perhaps gold plate, or I suppose steel, all with leather straps.
What I think we would today call a classy dress watch. Those were the classy and expensive watches grown ups wore.
Myself, being a teen, with teen friends, didn't want that. We wanted something silly looking Big, Chunky, multiple hands, divers dials, all useless crap, but hey, it's what kids wanted. Big, Loud, Cumbersome, things that did all the things you never needed, but you could show off to your mates with. Hey it's what kids do when you are immature
I passed that phase, and appreciated the very understated look. I started to appreciate subtle clean lines, tasteful, no need to have bling, no need to show anyone anyway.
However, I did notice the styles I left behind as a child/teen become more and more popular, and now I see adults wearing things I'd be embarrassed to be seen out the house with.
Like having a Gold BMW with a air wing bolted to the trunk, giant speakers, flashing blue LED's and bouncing suspension.
That's what most mens watches look like to me today. Like the thing a teenager with no idea of taste wears, and in a few years will grow out of.
But then, I guess we all have different tastes, esp in different countries, so, to each their own
