What do you expect? Everyone is jumping on the bandwagon, even smart phone companies. So they need to stay on top of the competition since Samsung has also plans, although HTC I think is the first to include this tech on their smart phones. So let's see if this could bring adoption in the next couple of years.
Doubt it. HTC is not on top clearly when it comes to smartphone competition. Samsung, Apple, Oneplus, Xiaomi etc are the front-runners from a long period of time which is why a blockchain smartphone from these companies could push adoption upwards drastically.
Phone usage is base on regions and there are regions where HTC sale more then the products that you listed, but the truth is HTC is one of the leading smart phone maker in the world and at that one will not anticipate less from them in the development of this smart device and just waiting launch of this device from HTC.
