"The customer will get their netbook sent to their home and they imagine to find something like a Microsoft desktop, but they see a brown Ubuntu version. They are unwilling to learn it and they were expecting to have Windows".

That's the core and the point. There's no point in trying to discredit what people (MSI _or_ Dell) actually say after actually trying to sell Linux computers - it's not relevant to the subject on hand.

Doesn't matter who you or I believe, what matters is who Nokia believes. And I am not surprised Nokia choose Windows first.
