Same here, here's my journey
- iPhone 3GS - iPhone 5
- Samsung Galaxy S3 - S4
- Nexus 5
- Lumia 930
I have to say there's times where I miss a certain feature from Android but I guess you just have to live with the differences. What I'm trying to do is find the quirks with some of the apps and build my own apps for the functionality.
This is the main reason I went to WP since I'm a .NET developer and would like to start building apps for the platform. (My first app - forums.wpcentral.com/windows-phone-apps/293116-pushbullet-wp-8-1-a.html)
