There's nothing new here for Windows Phone fans the Lumia 800 comes with Windows Phone 7.5 Mango installed, although I have not seen the operating system perform so quickly. The Lumia 800 lacks an expansion card slot, so the 16GB of internal user memory will have to be enough. Syncing my contacts book from Hotmail, I found 16GB was more than enough for scores of albums. That's another thing I like about this phone. Its high-definition speaker is located at the bottom of the handset, so you don't lose sound fidelity when you lay it on its front or back a problem with other phones I have trialled.
While it is a review written for a general reader, it gets over the idea of Windows Phone being exciting and new in a smart way, and highlights some of the special features that Nokia bring to the table for the platform, stressing the audio hardware (and accessories like the Monster headphones).
