Apple ads on TV always say that PC is for work and MAC is for fun, well if by work they mean this:
then I would rather work then have fun by flipping through albums, and making stupid youtube movies. What I am trying to say here is that, where ever you see some exciting stuff, like this research, they are almost always using Windows. MAC is used by web designers and web developers, look at c++ programmers, most of them either use linux or windows, and linux people ( at my work ) really are jealous of the visual studio ide and specially the debugger. Windows does make life easy. I dont want eye candy, windows moving up and down annoy me, I want to get the work done, so that I can go home and talk to someone.
