In the last 13 years, they've delivered three new platforms: the iPod, the iPhone, and the iPad. (I'm not counting Apple TV, since Jobs' "hobby" designation still very clearly applies). Each of these had extraordinary effects in areas that others either hadn't imagined, had imagined badly, or had imagined well but had written off as impossible to achieve. In every case, Apple's products - which went onto be world changing, industry revolutionizing, bazillion dollar successes - were widely panned at the time of their unveiling.
Not universally, to be sure. Some people loved the iPod instantly. But there were plenty of others who couldn't see past the $400 price tag and said "Sure, the iPod: idiots price our devices."
The iPad also landed with a thud, at least online. The people who got their hands on them said "no wait, you really have to try this, it's a totally new experience", but that had to compete with a loud chorus of "meh", which I certainly understand. Mine (an Air) may not be the most indispensable Apple product I own, but it's easily the one I love the most, and the one that gives men the best sense of where Apple is going. That said, it was also a gift, and not something I would have bought for myself. Not until I actually had it and had been using it did I see it less an an individual device, and more as the favorite interface for a (far from realized) cloud-based future of computing. My point is that the Apply routinely makes choices with a long-range logic that is far from immediately self-evident.
The iPhone came the closest to being regarded as revolutionary right out of the gate, but even there the excitement was shortsighted. It seemed like the biggest "breakthrough" was getting a handle on voice mail. There was still a lot of doubt about full-touchscreen vs. BlackBerry's then-dominant tactile approach. There was bitching about the lack of apps (third party development was web-only) and of course, the endless complaining about Apple's "failure" to include "basic" stuff like cut and paste. There was no GPS, no CDMA, and many of the individual components - from the phone itself to the camera to the battery life - were pretty crappy.
But all these problems resolved themselves with time. Meanwhile, the fundamentals remained astonishingly stable. So much so that in many cases, major updates were visually indistinguishable from their predecessors. It took most people a long time to recognize how far-thinking the essential design choices really were. And to be fair, it generally took Apple a while before their own development path realized the full scope of the platform's potential.
But that's what these are, platforms built for the long run. If the past is any guide three things should be clear. (1) They come with very well considered development plans (2) What come to be seen as fundamental features of the platform (e.g. the App store) go unannounced when the platforms launch and (3) the immediate negative reactions - of which there are many - tend to be very short sighted.
So no, I will not be buying an Apple Watch in 2015, and probably not in 2016 either. But if the past is any guide, I expect that Apple will be delivering on this for a decade, if not decades to come. By the time it's ready to untether from the iPhone, I can see buying in. I'm looking forward to it.
