That's alright, AROS runs quiet nicely on x86. For a price of a A1 mobo/cpu, you can buy a new low end laptop. Which can run AROS, of course. 
AROS is not even near to the quality, usability and robustness of AmigaOS 4. It's developed for many (10+ already) years by a tiny group of enthusiasts, part time, while AmigaOS 4 is commercially developed with two full time employed developers and a great many of contributors. Currently there is much more software available for AmigaOS 4, than for AROS, despite the fact that AROS predates the announcement of AmigaOS 4 with around 6 years:
OS4Depot as of today - 667 files.
AROS archives as of today - 11 files.
Giving this picture, no wonder why most of the people prefer to look at AmigaOS 4 and always {bleep}ing why it doesn't run on XYZ hardware.
