This phone is on my very top of the list. It offers excellent overall package. I've done serveral comparasons with other phones from SE, previous Nokia models, Samsung, etc. and this is by far my favorite.
I'm not really feeling the black though...the washed out black colour really throws me off...the white is very very attractive, an eye candy.
Build quality is top notch. An advancement in the camera functionality with larger apature and faster mechanical shutter...well of course xenon would be better like previous said but Nokia stated this one comes with the 3rd generation dual led flash that shoots further than previous led flash models...so this definetely looks very promising. And like previous said, without the xenon flash, leds can function as flashlight and it doesn't drain as much battery life as xenon thanks to the 1200mah battery supplied.
The design of the white model especially looks a lot like its bigger brother N97. Basically the difference is like S60 v5 with 640x320 resolution and touch screen vs S60 v3, patch2 with 320x240, non touch screen.
With all that said earlier, it's 375euro at launch, so it's a very attractive choice for users who doesn't need expensive touch screen phones like N97 or HTCs or Idou for at least $200 more by speculation.
I'm in marketing and I think Nokia has market this product quite well in the mid-end phone segment.
Let's just hope the final reviews of the official N86 is as promising as its spec.
