Man, I tell ya, this is a little off topic, but...
If Nokia made Android phones and the Lumia 1020 packed the 41MP sensor and JB 4.2, I'd already be gone.
I think iOS 7 is nice, so far, but it's not bringing a lot of core functionality with it. I'll continue to use it over either WP or Android because I can't stand the way Android is designed and I can't get WP in to a usable state for me right now.
So I think Apple has my business for another year. I like that I can pick up iOS and it looks nice and works perfectly without me having to spend any time trying to find the right "fit" for me like I do on Android. I like the physical home button, but Nokia has kind of solved that problem with the Amber update on Windows Phone.
I'm even 50/50 on if I'll be buying a new iPhone this year. I've got my lines staggered so each one is eligible for an upgrade every year so if I don't use it, I'm just paying extra for nothing at this point. I'm sure the 5S will bring an improved processor and GPU but I'm not unhappy with my iPhone 5.
I just feel like I'm frozen because neither alternative platform is really bringing anything significantly large enough for me to really switch. I'm just rambling now, sorry...
