Okay let me clarify what you are saying. By Maemo 6 you mean Meego 1.1 right? I thought there was not going to be Maemo 6 but instead it would be Meego from now.
However, what I read your posts to be is that the first Nokia device out this year will run Maemo 6. for the sake of simplicity let us call it N9. Then next year Nokia will release N10 which will run Meego. At that point N9 owners will be able to update the operating system from Maemo 6 to Meego. Is that correct? And if that is what you are saying can we really trust Nokia that you will indeed be able to update the operating system and not have to buy N10 to get the new operating system?
