I agree on poor management, likely also poor communication and understanding between software and hardware developers, as well as a likely high cost focus logic in a mass producer trying to shift over to high end phones/tablets/computers, a poor understanding of market, or at least a poor acceptance of the market changes when iPhone hit.

Regarding the OVI maps, they are on the N9, so in the end they arrived; not to excuse any Nokia failure to deliver on their promises
(I'm not aware that they promised the OVI maps for the N900, but I've been away from the forum for a couple of years.)
