My opinion is that most of the major manufacturers will produce a smartwatch. They might not sell in the same volumes as smartphones, but they will sell. One form factor does not fit all. Not everyone uses their device in the same way that you do. Many of my friends already feel that smartphones are too big; they are the people that the "minis" are targeted at. It's already the case that a range of screen sizes are good. The smartphone fills the "smallest screen" end of that range with the added benefits (for some) of being wearable rather than "carryable".
If you guys think they aren't for you then don't buy one. Your choice of device does not mean that a particular device won't be bought by anyone else. I'd never buy a windows phone, but some people said they'd be the (most attractive and) best possible device and asked why anyone would buy anything else.
