It's hardly limited to Apple fanboys. The Android folks are certainly giving them a run for their money as far as needless arrogance. The worst site I've seen to date was macforums.com. That has to be the largest collection of knee-jerk fanboy pricks in the Apple world. In fact, when I found this site, I bookmarked it and deleted macforums from the list.
Oh...and Apple doesn't need to chill, just it's cheerleaders.
