I defintly agree, if not the most underrated os in nokia phones, less to no advertesing than the shitty symbian os in n97( no offence I liked symbian during year 2004-2006)
I think Nokia sees Maemo as "beta".
Definitly Nokia doesnt want the usual iPad kiddie to own a N900.
Because THESE people will be very unpleased with it. Symbian on the other hand is at least stable.
