On a mobile device firmware and OS are very blurred... Its not like you can just pick up the n900 or any other phone and just install another OS on it! (well not easily anyway)

And as people are quickly forgetting Apple already had people pay for the ipod touch update and are planning on doing it again and I doubt its bringing much more functionality to that already crippled device!!!

Its not like this has'nt been done before. The question here is more would it be economically viable for nokia to use this model to deliver updates...

If the drivers were open source then I think the maemo.org community could pitch in and this would be a great driver for moving things forwards - cash rewards are a nice incentive...
