I don't think AROS has been aimed at Amiga compatibility for a long time, more at pushing the limits of the Amiga-style OS and API. They have traditionally eschewed emulation and legacy compatibility in favour of technical advances 64 bit support, multi-core, etc even if it detracts from the original mission of being source compatible. And I don't mean this as an insult, but if you're following AROS developments hoping it'll become a AOS or AOS NG replacement, you're probably going to eventually lose interest.
