My mate had it, returned it within the week as it kept freezing. Ive heard stories of them being pap and a lot of networks have removed it from their offers.
Also its quite bulky and the keys behind the music keypad are a little small.
If i was to get a current nokia get the N73, they are doing a music version of it.
Another good phone at the moment is the 3250, same software and very reliable. unlike the N80 - which i love to pieces but its so annoyingly buggy
