The Nokia Lumia 800 shares its exterior styling with the previously substantially less hyped Nokia N9, a Meego-based smartphone, although the screen size is reduced from 3.9" (854x480 pixels) to 3.7" (800x480 pixels) to conform to the Windows Phone spec list.

   The CPU, however, increases from the 1GHz ARM Cortex-A8 to the 1.4GHz MSM8255 Snapdragon/Scorpion which certainly helps add snap to the Windows Phone Mango OS.
The Nokia Lumia 800, although being the more expensive of the two Nokia Windows Phone offerings (the other being the budget Nokia Lumia 710) shares the Nokia N9's 16-bit AMOLED ClearBlack display whereas the Nokia Lumia 710 sports a 24-bit ClearBlack TFT.

    This being said, even though the colour depth is theoretically deeper than in the Nokia Lumia 710, AMOLED screens are seen as better than the older TFT technology due to the more vivid colours and better contrast ratios.
