Oh geez. Will this line of thought never cease? The poor horse is so mutilated -- is there even anything left to kick?
(If your imagination can take you no further than to see a watch as only a timepiece or jewelery just accept the fact you are not a creative person and think linearly. No shame in that, everyone is widely differently. It's what makes us all unique. But don't beat up people b/c they can think differently and reinvent and update a common object for modern life.)
A watch is by definition a timepiece.
These new 'wrist computers' aren't watches, they just serve a secondary function as a watch.
I agree with brianvictor7. Cell phones took the place of watches, and a whole lot more.
I cannot see the point in strapping something to my wrist, something I have to worry about charging frequently; just for updates - to which I can easily see if I just take my phone out of my damned pocket for 2 seconds.
There may be a market for this new 'watch'.
Personally, I just cannot see it yet.
