Exactly. Fanboy-ism is silly. I use Linux, MacOS, and Windows on a daily basis. Occasionally I have the pleasure of working with Solaris and other more specialized systems. Computers are tools, plain and simple. If OS X does the best job for what I'm trying to do I'll use it. If it doesn't I won't; I'll use something that performs better.
The same goes for the squabbling sometimes found in hardware discussions. Some fans love AMD, some Intel (no one loves Via

). Some love nVidia, some love ATi. It's silly not to just get the best available at the moment for the application at hand.
