Christmas Humor - I'm Dreaming of a Clean System

I'm dreaming of a clean System,
Something that fits on one CD.
Each component matches,
Not bits and patches,
Unlike 7-5-point-3.

I'm longing for a dream System,
Small, stable, fast, and trouble-free.
What we want, I think you'll agree,
Is called System 6-point-oh-3!
