Ha, the fun of fanaticism (no matter what it's targeted toward). Most of the time, I think back 'in the day' the arguments I'd get in with were PC users, I was an Atari user (Atari Mega STe) but was still somewhat envious of my friend's Amiga 500, since the Mega STe was almost on par spec wise with the A500, almost NOTHING used the 'e' bits of it, software wise. That and instead of adding extra resolutions to make it better, they stuck with the standard 320x200x16 / 640x200x4, and 640x400x2 required a special monitor. The stock OS was/is horrible on it as well. So eventually I got an Amiga A4000D, and upgraded the hell out of it.
I still have my Mega STe, but it's sitting in a closet unconnected, along with my TT030, and 1040ST. Though mostly because I don't have a working monitor for them anymore

Also I have a MiST with the ST rom on it that I haven't had a chance to play with.
But the arguments were rather fun back in the day. When it cost 250 bucks just to get sound that didn't completely suck on a PC, and you had to fork out some bucks for EGA/VGA so you didn't have the god awful colors of CGA.
Now unfortunately the 'Amiga Fanatic' is split generally between "We love our classics! Only true Amiga!" and "Oh, Amiga OS4 is the true descendant of the Amiga, PPC FTW!" and the MorphOS/Aros crowds. So, much like the way religions split off into different sects, (sorry to bring religion into this again, but it's so fitting) they all have the same base, but different interpretations of what that base is.
That's basically what happens when you have something wonderful that happens that affects a lot of people, and then it dies. The people who try to keep it alive all have their own interpretation of 'the true faith'.
Though it does show something about the Amiga/Atari's, etc. There are still a following of the platforms, 20 years after their parent companies disappeared. I honestly have to wonder if Microsoft disappeared tomorrow, if there would still be people 20 years from now saying "God, that was SO awesome, remember those days?" Sure there are people playing old DOS games to this day, but they aren't doing it because DOS was awesome to work with (god, who would EVER think that?) but because they were fun. The Amiga, and the way it does things itself is fun. Hell, I don't even play that many games on mine, I don't really use the apps either. I like playing with the operating system, and I enjoy seeing how some of the things it does have been copied over into newer operating systems.
Anyhow, I apologize for the long post, just figured I'd throw in a buck o' five for freedom...
