Thanks for the kind offer, but I've never owned a PC (and after much debate recently I'm even more convinced I never will...), I was under the impression that Aros was a bit like Classic OS4.0 (only better) and could be run on Classic Amiga hardware. Looks like I'll have to do a bit more reading up about just what Aros is.
I think I've seen somewhere that you use a Mac for the internet? If it's an Intel based Mac with OS X, you can test AROS on it either in VirtualBox or using the new Darwin "hosted" version (runs AROS as an application under OS X but this version is very new and so likely to not be as polished).
There's also a Classic Amiga version in the works, but it's far from ready (it just got to the point where it runs the boot shell a few days ago, but it's improving *very* rapidly - it's just a few weeks since it was totally non-functional).
