A preference for Macs doesn't have to be irrational. It may just be a different rationale from yours ;)

If you want the fastest CPU for your money, right now a home-built PC wins hands down. (Back when the G5 came out, it wasn't that easy - the G5 was definitely a great machine in its time, even though optimizing code for it was a challenge.)

However, people may pick a Mac for other reasons - maybe they like the operating system better, the attention hardware details (I'm sure the magnetic power plug has saved my laptop's life more than once) or just the looks. Practically everyone who buys a Mac knows that Windows PCs are cheaper, yet still they pick a Mac. They have their reasons.

We don't just look at horse powers per $ when we buy cars either.

So, cut the Mac users some slack - or would you like it when they start writing "get a Mac" in every thread about a Windows specific problem?
