Nokia N Series vs. E series both come from different groupings of mobile phones from the giant mobile phone company from Finland. They are not in direct composition with each other since they have their own unique markets. The N Series is packaged as a fun device with a plethora of multimedia features, while the E series is a more unadventurous design aimed at the typical businessman.
The most substantial distinction between the two is the keyboard designs that have been implemented on these phones. The E series phones possess a full QWERTY keyboard to boost typing speed, while most N series phones have only a standard keyboard.
Still, they also have dedicated player buttons for more accessible playback controls. The N series phones also have a far more impressive camera compared to the E series, along with bonus entertainment hardware such as FM and DVB-H tuner.
