unixguy, I'll let them speak for themselves and you can argue with them. Please note the x86 reference as well...

Darwin

Apple's open source projects allow developers to customize and enhance key Apple software. Through the open source model, Apple engineers and the open source community collaborate to create better, faster and more reliable products for our users.

Beneath the appealing, easy-to-use interface of Mac OS X is a rock-solid foundation that is engineered for stability, reliability, and performance. This foundation is a core operating system commonly known as Darwin. Darwin integrates a number of technologies, most importantly Mach 3.0, operating-system services based on 4.4BSD (Berkeley Software Distribution), high-performance networking facilities, and support for multiple integrated file systems.
