If Apple used motion (or solar) to recharge the battery, people would complain (even more than they are currently) about the thickness of the device. It currently only just fits under the cuff, any thicker and it would be far too thick. In a dress watch, thinness is truly very important.
But whilst I've heard this argument a lot, I'm surprised people are even considering it. Do they really think it will make a big improvement to the battery? I feel like the space used filling it with automatic charging tech could be better used if filled with extra battery. In addition, it turned out that the reported poor battery life of the Apple Watch was just FUD and that since launch, there have been very few (if any?) complaints.
Notification spam is another common false complaint. If you are bothered by notifications, that's your fault. The settings are very granular. You can use VIP in mail, if you're getting too much email, and disable as many notifications as you wish - there is no problem here.
Finally, the author complains that the Apple Watch will never be timeless, then straps on a Casio G-Shock. Enough said, really.
Pieces like these are exactly like the pieces we saw after the launch of the iPhone - how reporters were going back to their dumb phones or blackberries, etc. I suspect we will chuckle about this article too in years to come.
