Nonsense , you obviously don't know how Nokia marks his phones.

C- series are the cheapest models out there and they dont want to create internal competition with their own devices from other series

N series on the other hand are Nokia's top notch products and they WILL have the best hardware company can offer.

E- is business and X- is for youth so they might or might not have camera with autofocus etc...

oh btw Nokia recently announced that in 2011 they might release a true camera phone so I'm guessing it will have mechanical shutter and/or wide angle lense
