The thing is, it's not about beeing geeky. Sure there are some of us who would like it because it's cool. But lets take a look at it from this perspective:
Our company has 2 sysadmins. Both running linux. We have a total of 5 developers that need access to a
vmware console. All 5 are running Linux. The CTO has a Mac. If we were to license 8 windows virtual machines, thats 8x$300 of Windows Vista Business (because we don't have enough windows need to qualify for a license program; cant get XP; etc) + $500 av licenses +8 x $200 vmware workstation + the time and effort to support these systems....
"suck it up and by windows" works if you have 1 or 2 sysadmins. Telling our devs to run a windows vm would cause more of an uproar than yelling "bomb" at an airport
