Nokia haven't found its fault in mobile design yet, I think. Once upon a time, people like the Nokia's style of mobiles which are solid, brief,long lasting power and easy to use. But now, Nokia is learning to design some so called 'Intelligent mobile device' which are expensive, fat, short time power and with a lot of rubbish applications. As a result, this kind of thing failed in the market competition. Because end-users do not care about the 'Intelligence' of the mobile. The things they care are what they can feel with fingers,eyes and ears, but NOT CPU frequency or memory size.
In N9, I disappointed to see that there is a full size keyboard design. This will make the phone more thick and heavy. And the keyboard is too small to make fingers feel comfortable. As far as I know, no any QWERTY keyboard phone has achieved success in mainstream.
