I met Bill 2 times
once at the west coast computer faire San Francisco Civic auditorium 1985
I spoke with him and asked him about the high price of MS DOS
He said "For every copy we sell ten are copied illegally."
I thought he was personable and low key, this was early in his career.
In 1994 at Comdex in Las Vegas I met him again and had a similar conversation but this time I noted that the price had gone up and the software was copy protected. He smiled .. He was a big deal then and Microsoft was on the rise big time.
My impressions . he was a level headed geek with good business sense.
