One shouldn't let the notion of Jobs and Gates being "competitors" from being able to admire both of them. I admire each for different reasons. I think that has to be the case since they are pretty different characters: a closer analogy could be between a great batter and a great pitcher.
For some info, Gates wrote this yesterday http://www.gatesfoundation.org/annual-letter
(Was posted on HN but the crowd here seems to prefer something more controversial when it comes to Gates.)
