Nokia Lumia 800 trio

Many of Nokia's older phones are still available, but be careful: you can probably get better value for money by opting for a more recent model further down the range.

This is Nokia's previous best-selling Windows Phone of yesteryear, the Lumia 800. These phones featured a slightly smaller 3.7-inch screen and a good camera, and the first Windows Phone generation. They're unable to upgrade past Windows Phone 7.8.
