The Lumia 800 is a gorgeous phone. From the moment you pick it up, it feels like a solid, high quality, seriously well-crafted device.

Almost everything about the design of this phone is perfect, but not everything. The buttons, for example, are so flush with the phone that it poses a problem. Particularly the volume controls are problematic. By touch, you can't distinguish which is which.

I also take issue with the trend of placing the sleep button on the side, it should really belong in the top to prevent accidental pressings. That said, there are other decisions which I don't get-- Why is the USB port on top? That won't be useful for docking. Move that to the bottom, put it in the middle and the speaks aside it.

The display on the Lumia 800 is gorgeous. I love the way it curves, and it's Clearblack AMOLED. What that means is that blacks are, really, really black. Try turning on your phone in total darkness, and it'll look like the tiles are floating in your hand.

The camera failed to impress me. Sure, it takes solid shots, but for the hype they created for it, and especially when compared, inevitably, to the 4S, it falls short. It's a really hit-or-miss camera. It can create beautiful shots, but it probably won't 60% of the time.

I haven't had much problems with calling and reception, and was actually pretty good. The speakers are loud and clear, and what more do you want, really?

Performance is typical of a Windows Phone device-- it's good. You won't notice that 1.4GHz processor in daily use, but as soon as you start playing games, and especially if you had a first gen WP device like me, you'll notice that it renders every much smoother and better. App also open a bit faster, but otherwise the performance is pretty indistinguishable. And that's a good thing.

Windows Phone Mango is very good, and has a lot of things going for it. The tiles, groups, the animations, they all make for a really fun experience on the device. There are still some annoyances for me, but I think Windows Phone is now equal to iOS and Android, or even superior in some ways.

Battery life is not impressive. It gets through the day, but with heavy use it might run out before you get home. Nokia says they have battery improvements on the way, so that's something we'll see.

The WP7 ecosystem, contrary to popular belief, is great. There are some really quality apps out there. It might not have half a million apps but it's growing, and growing fast.

All around, I think this is a great phone that will please everyone. I would recommend this over an android phone anyday, but the iPhone still poses some fierce competition to it.
