They have been called stupid sheep or more recently iSheep, brainless or "disciples" (translation from the word that is used most often in German boards, Apple-Jünger").
Don't forget the ever-popular "Apple Cult."
And even in the mainstream press, journalists can't seem to avoid "Apple Faithful" or "Apple Devotees" whenever they write about the company. It can't be about great products, you see. It's gotta be about some kind of magical brainwashing or religious fervor.
Speaking of religious fervor, when do we get to start hearing about the "Google Cult?" Because their fans certainly make a lot more noise on the Web these days. Verge, Engadget, Wired, CNET, Gizmodo...I can't even come to MacRumors without hearing about how "teh awesome" Android is and how much Apple sucks at pretty much everything.
So please explain again WHICH SIDE has sooo much hate?!
Fortunately this forum has an Ignore list so I don't have to read the vitriol from some of the more dedicated and excitable Fand...oops, sorry...Android fans that camp out here.
