Yes my ideal Amiga would be a 1 GHz 3.9 setup to be honest. I just think that if i'm going to be breaking compatibility with my Amiga by using AROS, then I might as well just use Windows instead.
1. AROS for Amiga68K is in the works. Goal is to run AOS apps on those AROS based Amiga 68K machines.
2. OS4 and MOS both use a 68K emulator. You like running AOS 68K apps on those OSs, you shouldn't have any issues running AOS apps on a full blown emulator like JanusUAE. Emulation is emulation.
