Even though I am very sceptical about the RedHat purchase, I gotta admit that that this article points out some good things that can come from this. In any case I think that IBM overpaid a great deal for RedHat, and at this point I think it will depend on the IBM leadership, and the way they plan to integrate RedHat into the company, whether this buy will be a benefit or the biggest failure.
