the only reason i see for the n900 not being where other models of its time were in terms of sales figures: you cant lock it down. providers cant sell it at "€ 0,-" and prevent you from using a different sim card. phones are sold by providers. it never really matters what consumers think as long as they're not offered the phone by the provider. nokia intentionally did not include such "features". they will come with harmattan. this is why harmattan is the consumer-ready version. user interface, size, features etc are factors, but aren't as important as carrier support.
