Microsoft head Bill Gates was at Apple headquarters the day of IBM's announcement and later said "They didn't seem to care. It took them a full year to realize what had happened". The PC almost completely ended sales of the III, the company's most comparable product. The II still sold well, but by 1983 the PC surpassed it as the best-selling personal computer. IBM recruited the best Apple dealers while avoiding the discount grey market they disliked. The head of a retail chain said "It appears that IBM had a better understanding of why the Apple II was successful than had Apple". Gene Amdahl predicted that Apple would be another of the many "brash young companies" that IBM had defeated.
