@uppalpankaj- music quality through ep630 in n85 is very much better than n82 and n95 8gb. Since i have used all three phones with ep 630 in last two months, i can easily say n85 is way better than n82 which infact is a slightly bettet than n95 8gb. n95 8gb was particularly dissappointing for me. Such a flagship phone with low sound quality is not done.It was the main reason i thought of moving to n85. Bass is more pronounced. Also midrange is sounds way better than n82. I have heard n81 once, and i can safely say it sounds very much like n81, though n81 was bit more louder through ep 630.
Also, if u look at feature set of both n82 as well as n79, if u dont need xenon flash that much then going for n79 over n82 is not bad choice at all. Its feature pack 2 device as n85 which i kinda liking with all those menu transitions etc. You get better keypad in n79. Other drawback is lack of gpu in n79 though its application is very much limited as of now. Fm transmitter and navi wheel are welcome additions in n79. I am using fm transmitter in my car stereo with n85. Its effective range is less, only 3-4 meters. Browsing thorough menus using navi wheel is cool. But for camera centric device, get n82
5800 is different beast. First s60 5th edition touch device with large high resolution screen.Its a mid end touch screen phone. Nokia is coming out with a flagship n series touch screen phone soon after 5800. Touchscreen phones are not for me, hence i went for n85 .
camera quality is same as n82 if not better during bright daylight. Colours seems to be more vibrant on n85. Dual led flash is much more effective than single led of n95 though its not in the same league as n82 xenon flash obviously. You can use it while video recording too. Micro optics of dual led flash in n85 is better , hence its dual led flash is better than n96 , n79 as well as 5800xm. Though not camera centric, its camera performance is very good as of now. And with future firmwares, i am sure it will be improved .
Also , it can be said that nokia does not put all features in one phone. These people put most features barring one. Many people will appreciate xenon flash in n95 8gb as well n85. But that will kill the sales of n82.
