Amithlon type systems are likely the fastest emulation based Amiga experience you'll ever get. It's been awhile since I had one, but the speed was simply staggering. Of course, for the purists like Franko that don't consider anything other than a wedge shaped system with "Amiga" on it, it's not desirable. Will run circles around UAE, but will choke on stuff that attempts to hit the native Amiga HW. I'll take fast, quiet and efficient/more modern solutions any day of the week over old native hardware myself, but I certainly understand the purist aspect.
What I would like to see is a more modern "how to" guide and package to run Amithlon type systems. The original Amithlon was sort of a picky little bugger as far as what it would work on. If I understand it correctly, the newer kernels support a wider range of hardware and I hope to try it on this old AMD 4200+ X2 dual core/7800 GTX machine I have here collecting dust soon.
A more modern and up to date guide on Amithlon type machines would be a big bonus to the community if anyone is willing to do one up. I haven't been able to locate a reasonably modern guide on what more modern HW the newer iterations of the software supports, but it did work well on an old 2.8ghz P4 Dell I had.
Last time I tried it I was blown away at how nice of an experience it was, ran absolutely circles around any C= Amiga I ever had and I had both '060 and PPC Miggy's with gfx cards in the "good old days".
