That's not "off-topic." He was likening the iPod's closed software platform to the original Mac's closed hardware platform, and explaining that they shared an underlying strategy that we all know is consistent with Jobs' design and operating practices over the past thirty years.
Not that you'll understand, but I'll make an analogy. Let's say that you decide to take apart your Mac. You see a lot of wires and electronics that you don't recognize or understand -- all you understand about your computer is the keyboard and the monitor. You think that perhaps its some sort of alien being that has been incubated within your machine, and has to be destroyed before it infects someone else's computer. You rip and tear and smite the components... but then you wonder why your computer doesn't work.
In this case, you are wandering into a conversation without even the slightest comprehension of what the involved parties are actually discussing. You see parts of it, and you think you know what's at work, so you start flailing around wildly, laying waste to the average applied IQ of the thread's posts. But in the end, you only look like an imbecile incapable of comprehending the simplest connections between concepts.
Hello, are you done in there?
