I think that is very wise indeed. As a 'normal user' I've stayed away from all things linux thinking it was far too complex for me. N900 has convinced me otherwise: for the ordinary user, provided we get continue to stock extras and ovi, there would be no need to do anything with n900 beyond the user interface (yes, I know, one might choose to). And n900 does work like magic, apart from a few features which are still being worked on.

I'm still a little unconvinced whether I'd ant ubuntu on a device I make a lot of use of because it has that 'too complicated' assoication in my head.

I think Maemo is doing well with its current focus on UI - that's where Apple really, really excels. You need more bears in the system to say "That's easy" or "That's clunky" about the UI.
