Why would people "hate" it? It's largely irrelevant, puts electromagnetism in your wrist 24/7, requires one more thing to charge, looks "funny" to me, and I have never desired it, even if FREE. However, I reslly like my iPhone (an Android would be ok too, but I like iOS better). It is extremely suspicious to see the maker of iWatch to be having to point out hiw it's a worldwide success: it's not at all. A good product? Maybe. No maker is losing sleep over it. They may fear Apple TV and iPod and iPad only. But the problem is not the iWatch, but the fact that Apple has not done anything or even tried to do anything with anough balls to question a bugget market. The last time I though Wow, was with the ipad 2 release. Since then, we have a billion form factors for iPhone and "lock in" ..."ecosystem" prodcuts that want to draw a fee circles around their "captive market".
I am ready to leave Apple any moment another company pushes forward like Jobs did, bringing something that makes me reconsider how I achieve things.
Even simple thing like "Echo" are more innovative. Amazon serms to be innovating in many fronts even if they don't create huge new ideas, they try innovative things every month. Apple is just extrapolation of Jobs vision like a linear regression. When the market takes a turn, Apple will not be ready, and they certainly ain't leading it anymore.
