Actually I was impressed with what people do in GarageBand on ios. Unfortunately I haven't found anything comparable for Android. Only ridiculous $20/month apps.
Google would have to rip the heart out of Android and fix it for real time programming properly like OS X did way back in like 10.2?.
However, don't get me wrong, iOS isn't great--it's just at least possible. The fact that you can't actually send a defined packet (just a bag of bytes and you don't know how many until the call--"HAH! HAH! You device decided to prioritize something in the OS and your latency just quadrupled--sucks to be you.") to the Audio system on iOS is infuriating.
However, at least it's possible on iOS. On Android, not so much.
Didn't know. Looks like I'm little closer to replacing my android with iphone
2)The form factor of an iPad makes more sense in my music setup, in that I don’t need to haul podium or standing desk on stage as well as my instruments.
3. In producing tracks, most of my time is spent twiddling knobs, adjusting levels, etc, rather than dealing with external audio interfaces or doing fine grained, fiddly things with a mouse. But now iOS supports a mouse, so I could even do that...
For instance, an iPad would be a great place to experiment and get an idea down, and then you could bring the idea to your other, more professionally oriented tools.
