When I worked as an Apple laptop repair tech, that was almost nonexistent. 2/3 logic boards shipped in to be used for repairs on customer computers were faulty.

Imagine a laptop perpetually-stuck on OSX 10.2.4 that can't ever upgrade or it borks the system - that was my experience dealing with Apple laptops years ago as a repair tech. School system iBooks and PowerBooks were the worst offenders, and Apple had no discerning way to let you know which image belonged on which hardware, so we were always having to reimage laptops in hopes we picked a proper image for them.
