The N86 comes with a remote adapter if that's what's it's called where you can connect the headphones. It has the play/pause, previous, next, and the call button. I haven't used it or the headphones the phone came with.
I knew it was $400 at NokiaUSA and right now it's even cheaper at other places. Every week the price is getting lower and lower. A lot of people who've used the touch screens can't go back, or that's what they've said if it's true or not.
It won't be the last good non-touch phone even if that's what everyone is saying. Look at the E72. I don't text much anyway so it didn't appeal to me as much as the N86. Last good slider phone maybe as there aren't many slider phones anyway.
