The most perplexing thing for me is that Stephen Wolfram's kind of hyperbolic self promotion is something I normally see coming from companies that are trying to mask their lack of success. I actually think that Mathematica is an interesting and educational tool to use. Too bad it is a failure at affordability. Wolfram Alpha is not much to boast about in my opinion, but certainly an "answer engine" is a great goal and I would love to see more innovation here.
