Do you mean that you can digitally record Guitar tracks into Garage Band on an iphone over USB and transfer to a DAW later ?
Impressive- I noticed the LG Motion I purchased recently does decent Video Recording but no way to get digital audio in (via USB ).
I can see that the flexibility/open architecture of Android is a handicap for some things.
In the Audio Recording Industry PC Computers are usually configured specifically for Digital Audio Recording where with Macs-not necessary.
Truncating your music files on Android is an example-there's probably a remedy -but on iphone it just works.
The open architecture of Android is more flexible but more work to get everything working like the old Mac VS. PC debate.
Guess it carries over into the Android Vs. Iphone.
I like Android but would love to record 24 bit audio into my phone as a sketchpad for Guitar Tracks etc.
So for you Iphone is much more functional. I get it.
