Hi Thomas, it's too bad you don't have access to a Windows machine, WinUAE is light years ahead of the other "uae" variants as I've seen (I have to admit though, I haven't tested other versions recently). And Toni Wilen is very quickly fixing bugs and improving the software.
WinUAE on my i7 is crazy fast and even runs AmigaOS 4.1 Classic faster than my "real" Cyberstorm PPC Amiga 4000. AmigaOS 3.9 is even better supported with WinUAE and it's extensions, it's really a pleasure to use.
Take care,
Darren
