@blipnl: You might doubt there are different versions, but the reports here pretty much say otherwise no matter what you think. I doubt Nokia have changed the design, but they might have had to use different revisions of hardware components. And from my own experience, I have two N900s the keyboards are definitely different, one is like a matt finish and the other is like a gloss finish, I would hazard a guess that the shells were made from slightly different plastics because the rest of the plastic on the N900 looks ever so slightly different as well.
