Mostly because people like you can't see past the same old tired arguments and your own nearsightedness. There was nothing particularly zealous about anything I said. It was, if you bothered to actually read it, quite factual and nothing more, and only in response to a false statement that was made. I didn't bring it up. But what do you care? It must just be another Mac zealot.
No, this wasn't a thread to talk about any of this, but so what? Hell, isn't just about every thread here hijacked by someone to talk about whatever it is they want to talk about? Deal with it. And the point, which apparently needs to be made for you, is not how sweet and upgradeable the Mac is. It's just that it is, in fact, upgradeable, unlike what others have said.
Sorry to piss in your cheerios, but if someone is going to say something that isn't true, I'm going to point it out. Just like is done in any other thread here in any other topic. Just cause you're tired of hearing Mac people doesn't mean anyone else should particularly care.
