This phone is stunning. I had a Sony Ericsson K790a when I got this phone in, and i promptly returned the Sony for this phone. The screen is the single best screen I've ever seen on a portable device. I have great vision and I can't see pixels, the resolution is so tight that images and the interface looks amazingly smooth and stunning, even. The screen is easily readable outdoors, and doesn't have a serious reflective problem like Sony's K780a. This phone is actually smaller than the K790a, and feels smaller in the pocket. The K790 has a big bulge where the camera is, while this one is more flat on the back, which makes it far more comfortable in the hand.The controls take some getting used to, but once you get them down, it is pretty easy to navigate. Some might complain that it is slow, but the only place I really notice it is when viewing text messages, but it's not THAT slow, it's still rather zippy. Texting on the N80's keypad is a dream come true, the keys are responsive, and they feel well made. They are far enough apart to make texting and dialing very easy.I have had the phone slightly slide up while in my pocket, but not enough so that the screen was turned on, it needs to latch in the closed position a little more securely, but the sliding mechanism feels very sturdy and well built, and it is balanced when holding it to your ear or texting.The N80 won't give you fantastic battery life if you use it a lot for phone calls, but it should last a day or two without charging if you just mess with the interface, text, or make brief phone calls. After 2-4 hours of phone calls, the battery life will drop a few bars, but I've never had it die on me.It's not the best looking phone on the market, but the silver version (which I got) looks fashionable and not chunky or bloated like other smart phones. The camera on this phone is OK, but nothing special. Every picture I've taken so far has been relatively fuzzy, and out of focus, but the colors are accurate and the photos are still far better than most phones. The camera on the front of the N80 is nifty, but I never have a use for it. It's nice to have it there anyway.The expandable memory on this phone is important, because it can play tons of Flash games, music, and videos. Music sounds good on the speaker, and it is plenty loud. Callers sound crystal clear through the N80, and they say they can hear me much clearer than on my old mpx220 or my K790a. I had a terrible time hearing people on the K790a, the device just wasn't loud enough. It could have just been my phone though, I'll never know. It is more comfortable to talk to people with the device slid open, so you can hold it closer to your mouth and ear at the same time, but it works just fine without it open, and callers can hear me just as well.If you like options, this is the phone for you. You can adjust just about anything on it, and it makes it so customizable that you can set it up exactly how you like it. I'm new to Symbian, but so far I love it. It looks better than Windows Mobile, and, again, it's very configurable. I suggest downloading some themes from the net (on your PC, then transfer to N80). There are some really cool ones out there, and I found one I really love.The N80 doesn't sit flat on a surface, because of the switch on the back that switches the camera to macro mode. The top part of the phone rests on this tiny switch, which makes it kinda unstable and wobbly, but it doesn't bug me, I just wished it sat flat on a surface. The N80 has no volume rocker, which I am not used to being without. Instead, you use the directional pad to raise/lower volume. This works okay, but you have to take the phone from your face in order to change the volume, and this could have been easily solved with a simple volume rocker. In fact, only 2 buttons are on the sides of the unit, the power (on top) and the camera button (on the right). This can be a good thing, as you can pick the N80 up without pushing any buttons. On the K790a, there are so many buttons crammed onto the sides that every time i picked it up I pushed one, and it got annoying.I wish I got the black version, but the silver is nice too. Fingerprints show on the silver version rather easily, though the screen generally stays clean, as it is recessed. The shiny area around the buttons shows prints, but it cleans off easily, and Nokia includes a very soft cloth for just this. I wish the N80 came with a case, but they do include the headphones, USB cable, and a 128 MB memory card.In conclusion, buy this phone. It blows many other smartphones out of the water with integrated wifi, music over bluetooth, IR, and it's amazing screen. It may be pricey, but it's well worth it. I got mine from Nokia directly. Avoid TigerDirect, they sent me 2 Russian versions of the K790a in a row, and allow NO returns on cell phones.
