That probably would have meant that Commodore was still around (sorry, the Yeahronimo Commodore business is not what I call Commodore) and would have implemented a 'Ctrl-Amiga-Amiga' button on the Amiga keyboards. And Say would have grown into a version 10 or so, with some pre-sets for perfectly impersonating George Double You, Bill Gates and Madonna. It probably would have a 'sister' program called 'Sing'.
It also would probably mean that JPEG and GIF would never be so popular also meaning that, on web-sites, there wasn't the transparency problem most IE versions deliver.
