Seemed like the best way forward for amiga at that time. I think the lack of amiga chipset did kind of leave alot of people out though. Games was such a huge part of the amiga experience.
Today, you can install winuae on top of windows, remove windows shell and other things and get the same functionality along with the games. It won't boot or render as fast as an amithlon system, but I think being able to run any games is worth a few more seconds at boot time.
As I recall, amithlon was a bitch to get working on some hardware. You had to use a supported sound,video and network card I think.
Someone should post a list of the supported graphics, sound and network cards. I think I still have a couple of isos of amithlon around.
