Apparently Amiga and Commodore was put in there just to make the list look large, but you can tell VERY fast how hollow M$ is. Sure you can choose Amiga, but then you are stuck! There is no selection in the drop down menu for any Amiga browser. You have to make a selection of browser, so if you choose IE5 and Amiga you probably will get an automated email saying this browser is not available for that computer, please go back to school.
What gets me is the inclusion of Commodore. They must mean C64/128. Surely M$ would never think in their wildest dreams that a C64 or 128 would have a tcp/ip stack, let alone a webbrowser. But of course it does.
One more reason M$ sucks.
