iPad 1 got little traction, it was slow, had no camera, couldn't play HD mp4, etc. iPad skyrocket with iPad 2 which was so much better in every regard. The same with Watch, the Watch 1 (series 0) one had no GPS and was to limited. Watch 3 (series 2) has a dual-core processor, GPS, is water-proof and is a decent device.
The question is do I want to carry a smartphone and a watch? I switched from a digital watch to a smartphone like a decade ago, I don't need a watch. I can imagine switching back to a watch as soon as phone functionality gets inbuilt in Apple Watch and no additional iPhone is required.
It has been pretty much the same with pretty much every Apple product since Job's return. The initial version is a good implementation of the basic idea, but it always has a few drawbacks and is too expensive for the limited use cases it enables. Successive iterations then improve the product until it's amazing a few years later. iPod, iPhone, iPad, MacBook, McBook Pro, MacBook Air, iMac... They all went through this.
There are of course products that they didn't manage to improve in this way, e.g. the Mac mini or the XServer. So I will reserve judgement on the Watch for a while yet.
