Despite my issues with GPS, I really like the N86, for the Camera, the dual slide, the latest version of S60 3rd edtion.
But the N86 has one serious flaw, for me, that it shares with every other N series phone I've tried in the last couple years. If I'm in a noisy setting, with even just very mild background noise, like a cafe, the microphone picks up background noise and way over-amplifies it, in a way that is totally annoying for my caller. I found this in the N73, N79, N80, N82, N95, when I tested them. I don't know why Nokia just ignores this problem year after year.
My old 6290 is much better, because it's a clamshell, places the microphone closer to the mouth, and can therefore keep the gain on the microphone low enough not to overamplify background noise.
I see Nokia is now putting active noise cancellation in the 6720 Classic and the E72. Why ignore the flagship N series phones? Motorola, for all their problems, has been putting noise cancellation in its phones (crystal talk) for years.
This is a big disappointment. I was hoping the N86 would be different or at least a little bit better. Not just as crappy as phones from three years ago. I'm often trying to have phone conversations from cafes and out in the world (you know, where people use cell phones). It may, sadly, be a deal breaker for me. I really don't want to have to get a bluetooth headset (which I don't like) just because Nokia can't bother to put noise cancellation in their most expensive, highest end phones.
