I assume he's laughing at the "despite its quality" part. And I'd probably agree; while the user experience in Linux has improved dramatically, Windows's user experience is still generally better, at least in terms of "hours of use before the user feels the urge to do something that can only be accomplished with a command prompt". Food for thought: As Apple is keen to point out, virtualization should minimize the influence of network effects on your choice of primary operating system. And yet Windows is still going strong... Is it purely a matter of price or user education?
