I saw almost nothing of smartwatches before Apple's. I think I saw one two or three times in the world, and always at technical conferences. MP3 players and tablets, while far from ubiquitous before Apple's entry, were things I saw at least semi-occasionally out in the world. Smartphones were relatively common, although of course nothing like how they ended up being after Apple came in.
Remember, Apple was incredibly late to market with the product that saved them from eventual bankruptcy: the iPod. There was no shortage of MP3 players when the iPod launched.
And there was Blackberry and Palm long before the iPhone.
So, yeah, Apple is early here even if a year late. And they're taking their smart watch more seriously than any of their competitors.
It's amusing to be called an "Apple fan" though.
