Before winter break (back when I was an adroid user), I only knew one girl that had a WP7
After winter break, when I got my new shiny HTC 8x, my roommate also upgraded from her ancient phone to a white Lumia 920, her dad gave it to her ffor xmas and she was kinda confused (she thought her dad cheaped out on her since she didnt know about WP8) Until i started showing her all the features, shes still getting used to it but loves it!
And the other girl who had a WP7 also upgraded to a Lumia 920, her reasoning was coz they were "mad cheap, and reliable" lol
I saw a kid on the bus with a L920, and I know a student of mines who has a samsung WP7 (dont remember the model), I also met this guy at the club who had the same phone as me and we were both like "WE HAVE THE SAME PHONE!"
I have a friend who's an android user (and owns a macbook pro but really doesnt want an iphone o.0) who wants to switch to a windows, but he's waiting for Windows to get instagram to switch
