I've had a couple of Windows Phones, loved my Icon it was a daily driver unfortunately I'm switching to iPhone. Windows Phone doesn't allow me to pay using the phone at popular retailers, my bank no longer has a windows phone app, i like to use reward cards for places like CVS or Walgreens, movies and my local grocery store. All available on Android or iPhone but not Windows Phone. Apps on the other platforms seem to get updated more frequent, look nicer. One example WAZE much better on the other platforms. I think the other platforms have better games like Real Racing and RipTide. Windows Phone always outperformed the others. No lag or hesitation. I like the ecosystem and Windows Phone integrates better with my work environment and Office 365. I will watch closely and if things improve for Windows 10 Mobile then I might be back. Cityman and Talkman look like amazing phones with Iris scanner. Very cool. I use my banking app all the time, I use my reward cards all the time, I like top games, I want apps updated frequently, and I don't want to use third party apps for things like Nest or DropCam they usually don't have all the options. This has been a tough decision because I'm up for a new phone and I really liked Windows Phone.
Awesome first post. Very refreshing. Hate to see you go to another platform but you're always welcome to chime in.
