I went to a security conference about a year ago, and not being a security guy, I was surprised to see about half the people using Windows.
This being said, I am a little sad to see the prevalence of OSX-based laptops in 'hacker spaces', partly because I don't like Apple's practices, but mostly because diversity is one of the things that makes a hacker to me; the ability to make anything turn tricks. To see a monoculture starting to emerge is a little sad.
I tend to assume this has more to do with the piss-poor state of windows laptop manufacturers than with Apple. I'm sure those guys run Linux or Windows on their desktops, but seriously you expect them to put up with a heavy and crudware-riddled HP? A fragile Lenovo? A monstrously ugly MSI? A cheap Dell that falls apart the day the warranty runs out?
