Apple has produced some real bombs in the past. They are a company composed of people like any other and people make mistakes. They WILL fuck up sometimes.
I could add a few more recent products to that list, the cube being one, and Apple TV looking like another.
The Apple TV is a complete waste of space... unless you turn it into a usable media center http://mrcolinsappletvguide.tumblr.com/ I can only imagine that the patching process hasnt yet been blocked by apple (even in the most recent firmware) as it is only people hacking this system that are buying it.
The truth of a proposition has nothing to do with its credibility. And vice versa.
