I thought the same thing when i replaced my 486 for a brand new 233MHz Pentium. Why retire my old hardware when AmigaOS 3.1 could run on it as fine as it would on a 040?
Workbench 3.1 is incredibly lean, wouldnt it be cool if it could run on routers and such, you can easely squeze it down to 5-10 MB with a GUI.
The only problem is I could you run Firefox/OpenOffice on such an Amiga device, I think those apps are very important.
