When I went to buy any good phone with 5 MP camera and the NOKIA brand as my primary prerequists, N 79 was like gift from god.
Its sleek to fit in my money purse(something unusual for nokia mobiles). After using 6600 for nearly 2 years. this phone felt really good. Plus the wave secure which comes with the mobile makes the phone never leave you. So make sure you register yourself there as soon you get your hands on it.
The sounds is good and the 4 GB memory it comes with. The applications and great and so are the activation codes for numorous games on the mobile. No wonder its called Ngage mobile.
you have three colours of the back panel, which you can change easily and also your theme changes. that add some colour to your life.:)
And the camera. the thing for which I had choosen this mobile. 5 MP, it gives decent photos. It has a VGA camera on the other side. Quite helpful when you dont have a morror in hand.
Overall. I loved the phone.
