Well, it's hard to be a fanboy/zealot if you're using MS's products right? I personally don't have a problem with Silverlight/Vista/whatever on my macs but it's funny watching and hearing people say silly things like "Ewww! Microsoft?!?".
I work with a guy that claims the only things he hates in life are taxes and Microsoft products. Well, that was before I recommend he get a Windows Home Server to meet his media and file sharing needs to share files between his Macs and his kids Windows-based PCs.
Yeah he doesn't hate MS so much anymore.
