First thing about the phone is the good screen. Other competitors should learn from nokia to install such screens in their phones.
Let me make it short and simple but I wont miss any of the points.
The good - Superb screen capable of displaying 16 million colors. Good loudspeaker. Comfortable to type messages. Good battery life and ever realiable nokia brand name.
The bad - Poor quality headset and volume is low, Hard side buttons, Poor bluetooth implementation, Very low grade camera.
Overall the phone keeps up some of its promises but lets us down mainly in the media department. For the money you pay the phone is definitely good as a communicating device but there are other phones that provide more than the 6300 for the same price like K750 from sony ericsson. Bear in mind k750 is still ruling the mobile market with respect to the number of pieces sold and 2mp camera quality.
