This phone had promise: a 3.7-inch WVGA AMOLED screen, a 1.4GHz processor, a singular design in crazy bright blue and magenta, and a fancy 8-megapixel camera with Carl Zeiss Tessar optics, dual-LED flash, and 1080p HD video capture.
Let me tell you, specs don't always pan out. I have few complaints with the phone's interesting, gutsy design, but the camera quite frankly overpromised and underdelivered. You can see some of the photos and comparison shots in this gallery.
As for the rest, read all the pros and cons, and see photos and video in the full Nokia Lumia 800 review.
