Well , i recently had a chance to compare the two phones .. and compared to the N73 ME i have (with the latest firmware) .. N80 falls short on many things. . firstly , even with a higher res. display , the screen is actually quite smaller than the N73's .. plus the N80 seems to "lag" a bit ...
Also , with slight usage of all features like WiFi , bluetooth etc. etc. the battery hardly lasts over 10 hrs ... thats a hell lot less than my current phone .. Music ain't that good either , but not bad either .. Camera is ok'ish , but obviously better than most 2MP phone out there ..
Overall , the phone is not a good buy for 19k's .. my friend got it for much less (and in the process was about to be hanged) , around 14k's .. so he decided to keep it .. But if ur getting a new phone , then definitely get a N73 ME .. or even better a N76 , which costs more or less same as the N80 ..
PS : N80 seems to be phased out anyway ..
