7720 here. I could use the newer Live Tile sizes to build a killer music player upon upgrading, but for now I'm happy. Best phone I ever had. I had to inoculate it with Deox-it when the power button started to misfire, but it's in the race again.
Let me just say that all of you rock for sticking with a Focus. I still remember mine like yesterday. I adopted WP at launch and I've never looked back. I've gone to a Lumia 920 (at launch as well), but I still miss my focus in a way. It was my "first", lol. Kudos to you troopers who still frequent this thread.
i would be on 7720 but i manually updated to 7.8
