I think this post should be titled Why Configuration Management?, with a subtext of using Chef as an example. The main points the author is making are true of CFEngine, Puppet, Chef, and other config management software. The question of Why Chef? can be answered very simply: because the author likes it. Which is a perfectly valid way to choose your tool chain, assuming the technical requirements are met.
