While Mike means well, the picture he paints of the OS X world is a bit overstated.

There are security patches distributed by Apple on a fairly regular basis; not all applications play nicely with each other, sometimes requiring a "Forced Quit" but not often; Apple has had its share of manufacturing quality control problems, particularly LCD screens lately and there are products, like Apple TV, that really make you wonder "WTF?"

However, he is right about the product design being "on the inside" as well on the outside. Working inside a Mac is very much like working on a Mercedes, the engineering, sometimes "over engineering" is obvious.
