Linux

"There is a simple solution to that. Offer Linux PRE-INSTALLED!!!"

Yeah, like that's going to be popular. They'll sell even less!

Doesn't matter if it's better, people don't want it on their desktop in general, mostly because all that stuff they bought for Windows won't run on it. Fact of life I'm afraid and no amount of fanboyism will change it.

However as a footnote, Acer do (or did) sell linux pre-installed on some laptops, so the standard anti-Windows linux fanboy argument these articles always get is null and void (unless Acer have stopped selling them again, in which case that just goes to prove nobody wants it anyway).
