frnds should i buy sony ericsson k750i or keep my n 6630 with me....
as i want some modifications  in my mobile..

<< K750 >>

Pros :

+ Great Camera (2megapixel) + Torch/Flashlight
+ Great Battery Life (2.5days under decent usage)
+ Good Mp3 Player
+ Easy to use / Decent dimensions

Cons :

_ Small Screen
_ Not a Smartphone (if you are looking for Symbian-Smartphone features)


<<6630>>

Pros :

+ Smartphone features (Symbian enabled)
+ Big Screen
+ Great network reception (like other Nokia phone)

Cons :

_ 1.3Megapixel Cam (lack of Torch/Flashlight) with noises in indoor snaps
_ Normal Battery performance (2 days under normal usage, without listening to music files, otherwise will decrease to 1 to 1.5days)
_ Weak mp3 player interface / weak headphones for listening to music


Conclusion:

Its important to mention if you're looking for Smartphone enabled softwares, then you should go for 6630 or other smarphones, anyhow if you look for a great camera, good mp3 player and decent battery performance, all packed in a non-smartphone (considering to its relatively low selling price) then its wiser to go for K750.

anyhow, other non-smartphones options on that price range can be considered as :

Motorola V3i
Sony Ericsson W800
