I suspect you might well be surprised at the hardware used by people who use Slashdot. With a few exceptions, I think the majority of people here seem quite intelligent and logical but have somewhat of an aversion to change and unnecessary innovations.
Speaking purely for myself, I built my computer in 2011 with a i5 2500k and maxed out the RAM. Then I spent £60 on a low end graphics card because - why spend more when I have a console for gaming and a media player (WDTV at the time) for watching downloaded shows and movies?
I might be in the minority, but I don't think it will be a tiny minority.
