Yeah, the n86 slider is pretty nice. But really got into playing vnes and vbag on my phone since the form factor is perfect. And that little play in the slider is annoying. The keypad is kinda stiff, but not too bad. I'm sure it will break in a bit over time. I liked the keypad on the n82 better, at least could type faster. But the n82 would feel like typing on pins after so long.
As far as the camera, can't tell since using opera mini, but will check when I get home, and maybe post some pics I took with the n86. What I learned is don't go from focus to picture in one motion, you will surely blur the pic. Focus and slowly take the picture while keeping it steady as possible.
My only complaint with this phone is the camera button could of been better. It's not terrible since it is possible to keep it steady, but could of been better.
But overall can't say enough how happy I am with this phone. Before I bought it thought it would just be a n82 in a different case. Definitely a nice upgrade to the n82 in just about every way.
