Perhaps, but I don't buy the argument that Apple didn't know what they were getting when they hired him. The only hypothesis that makes any sense to me is that he was hired to make Apple's retail operation more efficient and profitable, which is not a surprising goal. This is why I say that strategic decisions come from the top, and it's the people who are hired to implement those decisions who get canned when the plan doesn't work out. Rarely does anyone at the top own up to a mistake.
These types of hire are done on vision. Browett would have given Apple a vision of a more sleek and cost effective retail operation and Apple will have bought into that. Unfortunately he did not deliver but rolled out the same crap that went down at Dixons in the UK. Everything he did was a PR disaster and that is not acceptable for someone in that position. If you fail to deliver what you promise as an executive then you should be fired and that is exactly what happened. I am not saying that there is not fault else where in the organisation for hiring this chap but he was a total disaster in that role.
