Hey, i am thinking about buying the Nokia Lumia 820, it is £105 from where i bought it and i was wondering if anybody had the same phone, the same phone in the Lumia line or knows their stuff about it. Just want to know how the windows os matches to other operating systems, is it easy to use, is it fast and smooth and all those types of questions. If you have any feedback in a way it will be highly apprenticed ;3
