Okay i've updated the list to REMOVE a few apps that are now on Android. Those revisions take longer for me because I don't have an android device anymore and i'm not as up to date on the google play store as I used to be, so I depend on Android users help to point out apps that are on Android now.
The removals are:
Avengers Initiative, Battle Cats, Baldurs Gate Enhanced Edition, Beat Hazard Ultra, Heroes of Order and Chaos, Pitfall! (2012 Remake), Puzzle & Dragons, Sonic Jump, Super Monkey Ball 2,
You Don't Know Jack
I know Baldurs Gate and YDKJ arent technically out, but I know they are both inevitably coming, and very soon, so I just removed them now so I don't forget later.
Anyone who hasn't checked out Battle Cats and Beat Hazard Ultra is missing out!

A handful of apps in my list are music production apps, and for a musician who wants to plug in a guitar, bass, or keyboard into their device for recording, amp modeling, and effects, android does not have an app that does what amplitube does, or garage band, or animoog. And I haven't found an Android equivalent to iTunes U. A lot of instrument manufacturers like Korg, Propellerhead, Fender, and Moog only release their apps on iOS.
Amplitube and Garage Band we're a big reason why I made the switch.
I think it's safe to say that Android has more offerings for business/office type apps, iOS has more offerings for music, and art.
Android is now getting something called iRig? Guess it is for recording pretty much anything at a professional level and has multiple input devices, including for guitars.
