It really is strange. I would never even look up an Android forum and go troll them. I can't imagine being *that* bored and having that *little* to do in life. Really bizarre.
Have you ever imagined that these "Android trolls" you are talking about, actually come to Macrumors because they have an iOS device? Or is it too hard for you to comprehend the fact that some people just prefer other products than your mighty iPhone?
I for one actually like iPhone 4 than most competitors right now on the market (haven't tried the SGS2, so no comment). But that does not make me defend the iPhone blindly. I will be a fool to limit myself to other options without actually getting to experience them.
