Not really good metaphors. Its not necessary to cover the intervening ground, to catch up technologically. Fix latency, app developers port and voila - Android looks pretty good again.
Doesn't matter how fast developers create applications that are amazing, iOS has already had all these years to create an already fantastic subset of these applications.
Doesn't matter how 'good' it looks - for the use case of music, android has simply lost.
That was actually my point. There's no need for Android development to cover that ground - it can just start where we are now, with cool apps that can just be ported over. Once the Android audio latency issue is addressed.
App developers LOVE to port, its another sale with small effort.
