Series 40 was one of the best operating systems built by Nokia. Unlike the Series 60/Symbian series, these Nokia phones are snappy and do not slow down with time. These feature phones were quite capable for basic phone features, but never evolved to the Facebook era. This effectively led to the mass adoption of touch screen based phone. If Nokia has solved the social app problem with this phone, I think they have a winner.
