Trust me the sound quality talk is all BS, all good phones above 10k are more or the same.
Sound quality matters only if its some cheap 5k phone.
Nokia phones are so boring, for the uncles, and not for the youngsters in vouge. Slim and sexy like the SE phones. So am with SE. In fact if I could afford the apple iphone, i would buy it any day over the fat a$$ N97.
All that application talk is also BS, you won't have enough time to use those $hit. You have to be a big time loser with nothing to do in life but just check out thousands of applications.
In fact if you get time to listen music on the phone, that itself would be great. And basic apps and games you will get on J2Me any way.
depending on your lifestyle buy SE or Nokia.
seriously get some phone and forget it and focus on more important things in life then the stupid phone itself, my advice from experience, you bet !
