I bought this mobile for Rs4500/- I found this to have the best features. It has good looks, it is ultra slim and ultra light. It fits comfortably into your shirt pocket and one would not even notice it. Some of the features are blue tooth, FM, VGA camera, MP3 ring tones, speaker phone. It has very good user interface and easy to use just like most of the nokia phones. I use it with a blue tooth head set and it works fine. It has 13 MB internal memory. Pretty good for all purposes.
The downside is that the processing is slow, you have to wait between key strokes. Keys are kind of hard and not so very easy to use. Battery life is not bad. Battery lasts for a day comfortably. It does not have a MP3 player, but has MP3 ring tones. It is definitely value for money. Most of my friends liked it.
