I honestly don't know, it depends on iOS 7. I'd like a UI refresh, it doesn't have to be a drastic overhaul, but some change would be nice. There are some features I'd really like that aren't available on this platform, I want a better way to manage files, having to constantly hop between apps gets annoying after a while. Also, I'd like to set default apps.
Windows 8 (or whatever it is) doesn't interest me, it looks boring. Android looks tempting but then I remember why I jumped ship in the first place, and the fact that I still have to troubleshoot Android phones (hardware & software) for people makes me not want to go back to that. It looks nice though.
