Plasma was before there was anything similar on Windows. But to be honest my perfect linux enviroment was kde 3.5. And I don't think "regular" people had any problems with uncanny valley. When I left for university I installed kde 3.5 on my parents' and my sisters' computers. My sister switched to windows 8 years later because of some apps she needs for work, parents still use Linux (but recently I installed them kde 5).
