Don't believe all the Apple hype about the Mac range of computers. I'm saying this as someone who has owned and used Macs for over the past 5 years now.
I'm not saying they are bad or anything, and actually like having my Macbook Pro when I'm on the road or visiting clients, but they are far from the miracle that Apple claim. They are in fact overpriced and underpowered, when compared to a similar spec PC. As for never crashing, all I can say is that's rubbish. My Windows 7 rig is more stable. Oh, and when you use a Mac you have hardly any freedom of choice, as Apple has a very tight grip on the hardware and software.
I can safely say, when I'm home and have the choice of either using my Macbook Pro or my PC, I use the PC every single time. No contest!
