[From Hans] I think I missed this but thanks to Hans for dropping me note that 25 Years Ago Today, Bill Gates Announced Windows 1.0 "Two decades and a half ago today, Bill Gates unveiled Microsoft's first operating systems. Oh, it wasn't for sale yet—no, no, it's still only 1983 and we wouldn't see Windows on store shelves until 1985." The Gizmodo after the jump.
