I've been doing something similar. I'm on my fourth iPhone, so I'm well invested in that ecosystem. I recently added a Galaxy S3 with a new line for testing purposes. I'm comparing both devices: if I prefer the S3, I'll transfer my personal line to it, and use the iPhone as the backup/test device.<p>I have no problem buying apps. I have a few apps I depend on, and many I like. My thoughts so far:<p>* The S3 is a superior piece of hardware, hands down.<p>* Most of the OS features are superior on the S3 as well, and the built in apps are as good or better than what's on iOS.<p>* The app situation is what kills the S3.<p>1) Many apps I depend on that are awesome on iOS don't exist on Android, and the "substitutes" are really poor in my opinion (for example, OmniFocus vs. the generic to-do apps)<p>2) Some of the same apps don't have ad-free Pro versions on Android as they do on iOS. Perhaps there needs to be a separate app store filled with more curated, paid apps? (Say Google Play and Google Pro)<p>3) Some of the same apps are absolutely horrible on Android. I suspect they are quick ghetto ports of successful iOS apps, not properly developed Android software. (Example: The Chive is pretty decent on iOS, and a bug-filled mess on Android)<p>Again, I was really cheering for the S3, but honestly, ecosystem trumps innovation.
