Discostu, I have never been insulting to you. I am not the only one on this thread that is pointing out your errors about the Macintosh.
You have made flat statements about the Macintosh that demonstrate that you are completely unfamiliar with the platform. You pontificate on the subject and continue to demostrate you are ignorant of Macintosh history, modern Macs, or its operating system. That is curable. Go get a Mac and use it for a while. I have pointed out your errors because someone might believe your incorrect information.
The fact that YOU saw a two button mouse for a DOS computer in 1982 is an assertion on your part. It probably is true. One was shown at the Fall Comdex in 1982. But it was certainly not a common piece of equipment shipped with every DOS computer. The Macintosh was not even the first Apple computer that had a mouse as an included input device... the LISA (January 1983) gets that nod.
