Ha, I've never, ever seen a Blackberry or Windows phone zealot. Sure, there are people who prefer lumia to apple, but I've never seen anyone resort to bitter name calling, or using boring and dated "isheep," "you're holding it wrong," taunts.
Not anymore, but you used to see them all over.
It is more akin to the old apple desktop users. Once upon a time, windows ruled everywhere and the only people who had apples were strange academic types who never set foot in the real world or artsy folks who needed advanced color and print capabilities.
"Real men" used PCs. In business settings, everyone used PCs. In software shops, real developers used PCs, the eccentric/cranky types ran unix/linux or at least pretended they did with cygwin, except for the graphic artist or designer - they used macs. In leisure pursuits, intelligent men played PC games, the unwashed masses used cheap consoles plugged into TVs, except for the lone oddball who played Marathon on the mac (presumably while sipping on wine and snacking on exotic, organic cheeses).
Since absolutely nothing was designed with macs in mind (due to an abysmal market share), these people had all sorts of difficulties - their machines couldn't connect to the LAN properly, they couldn't use the printers, they couldn't see the network shares, they needed things sent in non-standard (non-microsoft) formats, they couldn't read a proper floppy, their shoes were too tight, they couldn't get the fancy HOTAS controls to work, they only had one mouse button, software was only ported their way as an afterthought, etc... They were always either complaining about the above, begging for help for the above, or smugly claimed that they didn't any of the above anyway.
But deep down inside, they knew. They knew they were smarter, better, prettier than everyone else. They knew their platform was superior in every way. Why wouldn't all those meanies see it and acknowledge it? Obviously, everyone else was too dumb to see it, or not sophisticated enough to understand it.
They felt like an oppressed minority, everyone else thought of them as an oppressed minority who wanted special rights (we need our own special driver disk for the printer!).
Dare to put a pc in front of one (uhm sorry all we issue here are PCs), and they would bitch forever about crappy 'windoze' or 'winders'.
This is largely where a number of the positive and negative apple user stereotypes originated.
Fast forward to the present, in most environments you'll see pretty solid representation of apple computers. Even real developers use them - in fact, as often as not, I now find instructions and technical tuts using OSX examples that have to be adapted to Windows machines! (1990s self mind blown).
"Normals" are using them. Things don't seem so snarky.
The younger generation doesn't even understand some of the old code words, the PC way of describing someone with an alternative lifestyle as, "let's just say he uses a mac." "MacinTrash" means nothing to them.
Anyway, back to the point, Android is winning now, but they suffered a number of years as being considered second best, having no accessories built for their devices, having all mobile apps ported to their platform as an afterthought months after the hype died down for the iOS version, etc...

They felt like an oppressed minority, they were perceived as a whiny, minority who wanted special rights (iTunes should work with my droid!)...
And the beat goes on.
j/k
And Android kicks the hell out of Apple's expensive shit.
