The answer to your first question about a low tax environment is that, of course, it does help. But I think John would agree that the comparative advantage of R and D is really defined by the above-the-line costs, the costs of acquiring, developing, and retaining very highly skilled people. Canada is doing well in that regard, but we could do better. We find ourselves in a constant state of competition in that regard.
So then how do we leverage the advantages that are present? Here you asked about university relationships. Without a doubt, IBM's research model—which we're proud to say is one of the largest in the world, for a reason—with respect to some of the issues we're talking about here today is changing. It's almost transforming itself from being in the lab to going outside the lab, from a laboratory to a co-laboratory, and it's basically focusing the research around the problem. In other words, what we are trying to solve? And it's going to where the world offers the brightest and the best to help solve that problem.
Again, the gap is narrowing incredibly. On any number of these subjects, we have R and D operations in Brazil, China, as well as here. We can compete, but the gap is narrowing and it's a challenge.
I'll leave it at that.
