I bought a mac book pro once because I was getting into graphic design and bought into the hype that mac was the way to go even after being a windows user for 10 years at the time.

But...I still had to integrate with windows networks for administration work, had to use windows only applications for work, use windows for the bulk of my games...

Obviously I ended up dual booting with windows for a while, but in the end I just stopped using the mac os.
