No worries, enjoy Maemo 5 in the N900. Ar least for me is the best choice I can get in a shop nowadays. One day you will be able to give a try to MeeGo or MeeGo-Harmattan in your N900. If you like it, welcome,. If you don't, you still have the device and OS you paid for. If you like Maemo 5, I believe it is your own interest that Nokia invests heavily in the MeeGo and its way forward. In the current context keeping a setting of Nokia alone pushing Maemo would have been more than risky.
