Pros: Features "Bluetooth technology", to use for hands-free conversations. Considered especially lightweight, and features a handy camera. I also like that you can record audio, and then set it as your ringtone. It has a radio, as well. The battery life is considered very good compared with other phones.
Cons: I may be imagining it, but I don't think the image quality of the camera is as good as the 6101 model. I've seen the camera feature rated as low as 3/10, but it's still nice to have.
Summary: Newly released after the success and popularity of the 6101 Nokia model. Basically the same phone, but with newly added "Bluetooth" technology, and small differences - such as the look, or the new headset.
