I love my Lumina 920. I have had one since the day it was released. Then I got my surface RT and now I find my Lumia slightly frustrating. Not with the functionality but with the accessibility. I find myself flicking it and expecting the same action I get with my surface. When I want to email a photo or a link, I flick from the right looking for the charm bar before remembering that I need to access through the three dots on the bottom on the screen and navigate through the Menus. I like how when I access something through charms, it maintains a little selection of frequently selected persons to email or message. I don't have a lot of problems with the WP8 OS, I just now wish that it more closely mimicked the amazing W8 UI.
