Nokia's two new Windows Phones launched today, the Lumia 800 and Lumia 710, may share the same screen size, resolution, and some color options, but their design philosophy and user experience are more different than similar. The 800 model essentially squeezes Windows Phone-friendly hardware inside the N9's unibody polycarbonate shell, whereas the 710 was built with the express goal of offering a more affordable WP 7.5 option. That means it makes do with a 5-megapixel camera sensor and no special Carl Zeiss optics, its Windows keys are physical rather than capacitive (that may be considered an advantage if you prefer tactile feedback), and its shell doesn't exude elegancy and sophistication the way the Lumia 800 / N9 case does. The other big difference is that the Lumia 710 comes with just a standard LCD screen. It works fine in isolation, and if you prefer the white Windows Phone background it might be the better choice for extending battery life, however the 800's Clear Black AMOLED display looks markedly better in side-by-side comparisons.
