I'm not iball and I don't know the answer but I think the N770/N800 thing was an experiment to see how open source community could work with a hardware manufacturer in reducing the traditional costs around the Nokia products. If you read Qgils and Ari's statements it seems that Nokia is quite pleased with what they were able to achieve and the costs involved in product launch and development. As for the future I think Nokias involvement in the whole MID movement with Intel etc is a good indication that they are not dropping out.
