His last book was "Salmon of Doubt" published posthumously. Prepare yourself if you're going to read it, it is unfinished and ends abruptly, and you're left realizing, "He'll never finish it because he's dead." Very sad. I remember walking around my office the day he died and the majority of the people were like, "Who died?"

I watched H2G2 when it aired on PBS in the early 80's in my teens, and it changed my life, I didn't know humour could be like that. I have a signed copy of "Mostly Harmless" from an Intel Developer Conference he spoke at that I attended in the 90's.
