One thing that has always baffled me about responses to AROS is a lot of people are apparently incapable of understanding the difference between "os3.1 compatible" and "being limited to os3.1 compatibility". Sure, AROS does have a goal of being OS3.1 compatible, but both MOS and OS4.x are also os3.1 compatible. While not yet being as mature as either of the ppc "NG" options it does in some ways surpass both in terms of modern functionality and despite knowing this some people still drone on about the idea of it striving for os3.1 compatibility. And before someone gets up in arms about me saying this, no Im not suggesting it's better (or worse).
I also find it a little irritating that people who have no real idea about development, or have never experienced the amiga systems apis 1st hand are quick to dismiss it's apis as incapable of achieving certain things. Just because something hasnt happened yet doesnt mean it wont, or is incapable of it (Im refering to aros mostly here, but this applies equally to other amiga based systems).
