I recently renewed my contract and upgraded from a 6230i to a N80. Whilst the N80 does have some features which are useful, the exasperation I feel whenever the phone loses the signal (much worse than the 6230i), cuts me off (never with the 6230i), and doesn't allow me to do things like download the call log is sometimes enough to make me feel like throwing the damn thing out the window.
I have several friends who either have the N80 or 70 and they are also feeling the same - very angry and they feel it's the worst Nokia they have ever had.
I am not going to get a Nokia phone next time after this. Plus the PC suite software is pretty awful.
