I'm really glad my iPod has never locked up.. (like 20 times or so).
What makes this such an epic fail is not just that it's "locked up" -- no, it's completely unusable. There is a fix which involves taking it half apart to perform a "hard reset", after which it will work -- until you try to plug it into a computer, which will kill it again.
That, and the fact that everyone's 30 gig Zune, everywhere, seems to be having the same problem. I certainly don't remember that ever happening to even a single line of iPods.
the more complex the machine, the more chances it has to break.
That is a cop-out. I suspect it has more to do with the fact that despite problems like this, people keep buying Microsoft products -- so what incentive do they have to spend the extra time/money to get it right the first time?
Microsoft is certainly not the only one, though they are the most visible. Case in point: People bought new computers with Vista. Worse than that, a surprising number of tech-conscious people bought Vista itself.
