I once considered buying it but settled for WinUAE in the end. Amithlon and AmigaXL come on the same CD. Amithlon is supposed to be faster but rather fussy about the PC, video card etc... it's running on. Also it can only use Amiga drivers for printing etc... AmigaXL is supposed to be compatible with more types of PC configuration but slower than Amithlon. It is able to startup QNX progs from the Amiga workbench, giving some extra options for web browsing, printing etc... Another option is(was ?) Amiga Forever which is like an improved WinUAE. There was some controversy around this H&P, distributors of AmigaXL/Amithlon and Bernie Meyer, maker of Amithlon. I don't want to get in the middle of that discussion but I think that's what finally stopped the development of the progs.
