heehe I started reading this thread queit late, a good comparision, and using word brick,
in my words all nokias' are bricks because they are of much solid make than any of the SE, and I say regardless of the fact I use SE K550, but guys if its just like that comparing good eye candy design then samsung and LG are better than nokia or even samsung.
so buddy gourav, its upto you as uppalpankaj said earlier with a very good and neat comparision what you wanna buy, after reading through suggestions, because any problem comes up its your head which will be tensed we would be just helping out.
and for my words, N82 being Symbian and equally priced to K850, is better, because after paying so much you will like to keep your phone atleast 2 years, and by that time you yourself would not know what apps you loaded, and symbian will be really able to handle things well.
Even then with good java base support and cool designed K850 you wont regret, keypads of nowadays mobile are good(keypads of 5500 sport is what no company would wanna repeat), and you can get used to them quick and easy. and light weightness of K850 would make it have even better feel in your hands.
Good Luck in whatever you buy.
