I agree but from point of HW manufacturer speed is quite important. If you can put HW that is couple of dollars cheaper /device (slower cpu & gpu but more optimized code&OS) than your rival you can make quite difference in profits. This is one reason why I think that Nokia will never ever use the newest and leanest HW. In addition it could be bad business decisions because of shortage of these newest and leanest components. Big promises and small output of device not good for company size of Nokia. Nokia has probably (after "The lean" Toyota ) worlds most efficient manufacturing and logistics channels. Smaller companies will use newest HW and try to compete with just pure MHz and Gb specs. IMO it´s almost as stupid as M.pixel race of digicams.

But it´s true that people tend to over emphasize speed quite much and we all should remember that our bias (quite probably) here in TMO is quite different from Joe Averages.
