Lots of people rip on macs because they don't realize how flexible they are, perhaps not in terms of hardware (although thunderbolt will change that), but allowing us to have our choice of OS, or if we really need to, use multiples at the same time.
For instance someone will ask me about a specific application, then look at my machine and say "oh nevermind your on a MAC" (you know
how they say it

). I simply say "so what?" and go to my dedicated Windows XP OR Windows 7 VM in the 2nd or third spaces running full screen, full speed.
People get pretty nervous when they see a skilled MAC user in action, flipping between environments, or perhaps using terminal. They start to panic, wondering "WTF is this guy doing with a MAC when I thought only Windows users could operate a computer...and why is this MAC not in a coffee shop?!??! What's going on!".
And yes before someone comes in and says "durr eddy MAC stands for Media Access Control har har I think you meant Mac durr", i'm fully aware of the difference, so thanks.
