OLPC has done amazingly well. I can't think of a previous attempt at non-profit hardware, and I believe that going from nothing to half a million units shipped in three years would be considered a success even in the commercial realm. I can't say I'm thrilled with the direction that Negroponte has chosen, but it at least provides some competition to the open-source solution -- system and activity startup times have always been weak points for Sugar.
