I should have been more precise. Due to the fact that Apple controls the basic platforms and the operating system, you have fewer conflicts between hardware and OS (in my experience). And, of course, you can buy peecee parts that are just as high quality as Apple stuff, but you have to do a good amount of research to find out what they are, and it's unlikely that you'll buy an already built system that has those parts, meaning you'll have to build it yourself.

My point was that my personal experience supporting both peecees and Macs is that Mac laptops have fewer problems than peecee laptops. And it is my belief that this has to do with the fact that laptop-specific hardware support was an afterthought in peecee OSes, even (and, perhaps especially) including your various Unices as well as MS Windows. (And you can't build a laptop yourself to get higher quality parts, either.)
