Kommander: Glad you're enjoying the new update!

Steve: That's about the size of it. People are seldom thrilled to pay for an upgrade, but we hope most will be satisfied with the process. Charging for upgrades every so often is a necessary part of being a sustainable business. We wouldn't be able to add major new features like Bluetooth support or Airfoil Satellite, if we couldn't recoup our investment with a paid upgrade.

Enough rambling - thanks for the kind words and enjoy Airfoil 5!
