I've used the N80 as my only phone for about ten months . I would give it very high marks in every respect except one: still photography.
No matter what options I try, I am unable to take a sharply-focussed picture. The daguerreotypes of Matthew Brady, circa 1860, were far superior.
It has taken me some time to own up to this deficiency of the N80. The 3.2 megapixels, I thought, would guarantee high-quality photography. But the pics I took with my earlier, lower-resolution camera phones were every bit as good.
Videos, on the other hand, have been more than satisfactory. But that may only be because I am still amazed that a cell phone can actually record movies at all.
With this proviso, I can highly recommend the N80 to anyone who needs a capable, all-around phone that will do what you want it to do, and who doesn't expect his snapshots to be published in the National Geographic, or hung in the National Gallery alongside the photographs of Ansel Adams.
