Most comprehensive review of the Lumia 920
Here are a series of 7 videos that cover all aspects of the Lumia 920 in serious depth.
Kudos to the reviewer for such a detailed look at the unit with demos. It will take you a couple of hours to watch all of them! But you can pick the video you are most interested in.
If you are two minds as to if you want to buy a 920 then this will help you decide for sure.
For me it highlights the quality of design and engineering Nokia have put into this awesome phone.
For instance I didn't know this unit had 3 microphones that work together to produce distortion free sound recording and that the phone adjusts the colour saturation of the screen in bright sunlight.
