"There’s no question that the Apple Watch is the most capable smartwatch available today. It is one of the most ambitious products I’ve ever seen; it wants to do and change so much about how we interact with technology. But that ambition robs it of focus: it can do tiny bits of everything, instead of a few things extraordinarily well. For all of its technological marvel, the Apple Watch is still a smartwatch, and it’s not clear that anyone’s yet figured out what smartwatches are actually for.Apple Watch: the definitive review
If you are willing to go along on that journey, then you’ll enjoy the Apple Watch. It is a bauble, after all, and baubles delight simply by their presence. Apple will update the software, and developers will make apps, and Google and Samsung and Microsoft will release competitors, and the people who love technology will have something to buy and argue about, talismans that display tribal affiliations.
But that’s technology as fashion; it’s not quite yet fashion itself. If you’re going to buy an Apple Watch, I’d recommend buying a Sport model; I wouldn’t spend money on how it looks until Apple completes the task of figuring out what it does."
