Personally, I don't see the reason for all the fuss about AROS ...
OK, I agree that's a serious project and the people involved are surelly skilled ...
But I have only one complain : Did you ever tried to run it on a 486 on the past ?
Before you laugh at me, let me say that I tried AROS some years ago when I have a 80Mhz 486 and that thing was damn slow !
Are you blaming the 486 ?
Don't.
On that same 486 I also run win95 and that was fast !
Usable.
OK, AROS is AMIGA like, now we have GHz CPU, blahblahbla, but I was totally putted by the lack of optimization of AROS ...
I really looked like a 68K emulator (which it isn't!)
