I switched to Android after 7 years of iOS
I did the opposite and can't believe how much better my life had gotten because my iPhone is just a simple tool that I use for communications and don't think about it as a project.  With Android, I always wanted to tweak silly things and run Cyanogenmod because the handset firmware was always so bad and vulnerable.  On several occasions I'd bricked my phone requiring hours of recovery, or had transient failures of cell service and communications issues.  I guess if you have the right level of discipline, apathy, or use a Nexus device that may be more Apples to Apples (harhar).
