I'm going to come right out and say that I don't like Symbian anymore after having used Maemo. This doesn't mean Symbian is any less capable than it was before, but it's just so hard to think about going back to it after having used Maemo.

Keep in mind that I haven't used Symbian since the N72 so all the advances since (and it probably doesn't even remotely resemble what I used before) have been mostly ignored by me.

For me, Maemo was the attraction, not the Nokia brand. I also don't doubt that we will see more of that camera in future Nokia phones since they have a tendency to stick to their hardware inventory for years.
