I would like to see a "put-up or shut-up" contest between Amiga OS4 and MOS1.5! There was one a couple years ago that never happened. I don't remember why?
Let me go out on a limb here and suggest that it's because neither of those OS's are finished yet? Having an OS4 vs MOS1.5 contest should be about as productive as those Vista vs Leopard discussions I've been seeing lately (ie not very much...)
