Lets remember that over the years nokia has continually made such weird and unexplainable feature and design choices that its insane some of them. So this cpu choice really doesn't deviate from this trend all that much. It doesn't make sense to get this caught up with the cpu when stuff like call log bug, no open window in web browser, lack of firmware nam updates, horrible built in email app, on and on etc. Doesn't make it right, but us nokia fans have been dealing with this stupid crap forever. I'm still interested in n97 for its battery, camera, screen etc.
Those things don't disappear because the cpu is not next generation.
