OK, what advantage is there in switching to Android for a N900 user?

I am due an upgrade and could get a dual core but apart from faster processing, which the 18 month old N900 can't do a lot about, I still feel the advantages of the N900 out weigh any Android device in my view.

It still has a superb browser, decent sat nav, a fm radio and transmitter, a good media player, plus a load of decent apps and also the WebOS games.
