Indeed, I rarely have any kernel panics, or system crashes on OS X, and especially iOS with the latest iPhone. Other than iTunes, their software (that I use) has been pretty good lately.

I've actually had more problems with the hardware. My late 2011 Macbook Pro was just returned from the offsite Apple Repair with it's 3rd logic board (that being said, it's still under an extended warranty from Apple, which is at least a consolation prize).
