I bought the Lumia 710 on Wind Mobile for $199 about two weeks ago, here's how it went

The design of the Lumia 710 is not as striking as the 800 or the 900 but it is still good and proves that even on low-end phones Nokia can produce well designed products. The back is removable and has a matte finish. All of the ports (usb and headphone) and the power button can be found on the top of the device.

The display of the 710 uses Nokia's ClearBlack technology. The display is vibrant and can be viewed even when outside. Over-all the display is pretty good.

The Lumia 710 only has one camera. The camera is 5mp with a flash. The camera by itself is good, but what makes it stand out is the extra camera functions from Nokia which include things like panoramic and smart group shots.

Call quality on the 710 is good and I never experienced any in-call problems or dropped calls.

In my use, the performance of the 710 is good. I played a few 3-D games on it without problem and never experienced any lag anywhere.

Windows Phone 7.5 offers a great user experience with no lag and smooth web browsing. Tethering also works well and I was able to connect my netbook to it without any issues. After using this phone for a few minutes I fell in love with Metro because it is so simple and smooth to use.

The battery life of the 710 is great and I was able to get about two days of battery life on it with battery saver on.

The Windows Phone ecosystem obviously need more support but I was able to find what I really needed just fine. (minicraft is great)
