N80 has WiFi, N73m doesn't. Whereas N73m ships with a 2GB card and has Carl Zeiss lens for camera. N80 doesn't have that. So based on your requirement you can choose. I have an N80. It rocks man!!!
N80 is not available now.. Instead N80IE (IE stands for internet edition) is very much available.. How did you settle for an N73ME instead of N80? Both are for completely different uses..
N80's wifi reception is not very good.. if the signal is less then it wont get connected.. i mean only if the signal strength is good then wifi works... and N73 has a superb camera and good music quality too.. better than N80 man..
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 ..
