Jef Raskin (born Jeff Raskin; March 9, 1943 – February 26, 2005) was an American human–computer interface expert who conceived and began leading the Macintosh project at Apple in the late 1970s. (wikipedia)
I've moved on, grown and learned in the years since then, and am designing interfaces that make the Mac's GUI feel as clumsy to use as the Mac made the old DOS-based systems feel primitive.
