Hi there, I am about to buy the iPhone 4S and remember seeing demos about apps sharing through iCloud on the very last Stevenote. 

I'm pretty sure we can pay once for the apps and then go ahead and install them on our other iDevices for free. But does it apply to iDevice apps only? What about Mac apps?
So for example, do I have to buy Garageband for my iPhone if I already had it on my Mac?
thanks
