Nokia's problem may be that it is sticking to its original brief for an Internet tablet and only responding to criticism of their implementation of that brief, rather than responding to criticism of the brief itself. Lots of people have given constructive criticism of the tablet concept but, really, the N810 is a clone of the 770 with some additional features, and the 770 was produced in the isolation of a lab. Obstinacy does nobody any good. It may well kill Nokia's internet tablet.
