I don`t quite see what Amithlon has to offer, WinUAE, FS-UAE and UAE4ALL have way better compatibility and functionality, not to mentional flexibility - as user you can decide yourself how much host OS you want under them. I use FS-UAE on my Powerbook daily, and for most productivity programs that works with RTG it is hands down the best option I have. But for games, animation and music where timing is critical, the only satisfying options are real Amiga, Minimig and the MIST.
