I am SO tired of people trying to make fun of that phrase every single time there's a bug. When Steve Jobs said "it just works", he did not say, "there will never ever be a bug in our software ever." There will ALWAYS be bugs in software and that will never change.
"It just works" meant that you don't have to configure a bunch of settings or go through any kind of long and annoying process to use a feature. You're being immature when you continually make fun of a company by taking a phrase in a direction it wasn't meant to be taken.
You are right, Steve didn't mean it that way. But the problem is that majority of Apple buyers tend to think that "it just works" means that OS has no problems.
