Amazing!

Powerful, smooth, and responsive — on my second-generation iPad, no less — this app makes making music easy and accessible and yet sophisticated. GarageBands performance blows away the rest of iOS in terms of speed and fluidity, obviously optimised for real-time operation even on the oldest of iPads it will run on. Thank you, Apple!
