Mac has many things that make owning one so great.

-Sleep feature on laptops is great and the flashing light when sleeping is like snoring

-Resell value is really high. It just like BMWs of computers. My laptop i bought for $1500 is now 1200 and i bought it a year ago

-The run on Darwin Core which is a open source version of FreeBSD that has been changed and changed again. With open source core OSs you don't have to worry about memory management problems or things along those lines.

-Alway comes with the newest and best technology built-in

-Parts have been tested and tested again to last as long as possible. I have noticed that they have changed hard drive manufactures from older models to newer ones.

-The displays that come with the systems are extremely high quality. To replace a laptop's display isnt cheap.

Lastly I have gone through many PCs but I still have my old laptop from 5 years ago and it still runs like a dream. My wife uses it and has no issues at all.

Even though MacOS X's core is open sourced, that doesn't mean that it has memory management problems. The memory management isn't even based on the FreeBSD kernel-land space. The Mach kernel handles the core system in the kernel-space. Apple only used FreeBSD for its userland space, which includes user management tools and UNIX system tools implemented in FreeBSD.

Darwin is essentially a object oriented Objective-C based fusion between FreeBSD and Mach.

After years of debating I finally broke down and bought an IMac about six months ago and am kicking myself every day for not having made the decision earlier. Everything I have plugged into this thing has been recognized no matter how obscure...no drivers no downloads. To date this thing has never crashed and I'm a power user including video and music applications. The extra money pays for itself in far fewer headaches. I have over 10 machines in my house (each of my 3 kids has one, wife has a laptop, I have two PCs + 1 laptop, my IMac, etc) and can tell you I am ready to throw each of the PCs out of a window. For anyone considering the switch...make it. Don't bother with the Parallels just pull the plug completely and become a Mac user.
