And I know, Windows is beyond reproach, and BSODs are really the fault of OEMs, but I've never seen Linux kernel panic--not even on the same hardware Windows couldn't handle.
Not trying to start a flame war, but I really think it's misleading to say Windows "just works".
"Just works" is subjective so it shouldn't be a purchasing factor.
More relevant to this conversation, Macs have a wide (and presumably well-deserved) reputation for quality, and Windows PCs have a wide (and presumably well-deserved) reputation for cheapness (both in the quality and cost contexts). Sure, that consumer Dell you bought might boast better specs, but these objective metrics do a bad job about predicting things like product quality or overall satisfaction.
