I think the developer and many others are missing the crucial problem with this product and with this type of idea in general: interacting with a watch that does anything more than tell the time and date makes the wearer appear to be a giant dork.
This has not changed since the days of the early 80s calculator watch; any consumer foolish enough to bring attention to their “cool watch” is immediately singled out as a dork, nerd, geek, or generally friendless loner/brainiac type.
Don’t even get me started on TALKING into your watch.
