* Actual ran Windows 10 on HDD in an old refurb tower for a while, before buying an SSD to act as boot drive. It work acceptably for me, although I wouldn't get a new computer with it (If you getting a SSD to install Windows on, I would recommend getting at least 250 GB, even if it is just a system drive). Also, I wouldn't give up on HDD yet, at least for data storage.
* I think the reason Windows 10 was brought out so quickly was because everybody, particularly businesses, hated Windows 8, which was designed to "unify" the desktop and mobile devices, to go along with MS's push into the smartphone market. It might have worked, but by the time Windows 8 came around it was too late and it eventually died (although Microsoft's own surface line seems to doing well, can anybody talk about the Windows 10 experience). Also, the whole industry is moving towards
development model of release it as shit now and slowly engooden it over time, so no surprises Windows has done that as well. And I would agree that it has actually worked in favor Hopefully the death of Cortana portends to the death all the other exceptional individual digital assistants.
Also, these thread reminded of this video on why Windows 10 and its bugs:
