I know how the OP feels. I'm am so in love with my L1020. Just last week, I broke one of the metal contact points on the wireless charging cover. NO ONE has them in stock and the Microsoft Stores in my area wanted to give me the Camera case accessory, but as much as I would love to own that, it doesn't replace my wireless charging.
I don't miss any apps. I'm not having performance issues. BUT.....I do want another flagship with a camera equal to or better than this one. I'm a closet photog, but the camera is what brought me to the phone, and what will cause me to hold on to it. 900-->920-->1020. It has to get better hardware wise. It just has to. I can't go back to Android. iOS is NEVER an option.
Sorry for the rant. I just feel your pain. Best of luck to you.
