I'm sorry, but what?

The reason Nokia wants to use Symbian is because it is more "mature" than Maemo.

N97 is better "hardware wise" than N810, but software is up to the user. RX-51 is (IMO) going to be much better than anything, but that should be obvious.

I can't understand how "future N-Phone will never be as good as my current N810," because that is like saying a Windows 7 Quad Core will never be as good as my 30mhz DOS Box...

I'm not sure what you were trying to say, sorry...
