And apps are less expensive, because it's a totally different market, and you will be selling way more than desktop apps at these prices. Sell 10.000 Cubase copies for the desktop for 599€, or sell 100.000 copies of Cubasis for iPad for 49€, it's almost the same... and if your business plan allows it, you can even give it away for free. But then the desktop app clients have to pay for it, someone surely has to.
@ musical android: Thanks dude. Just installed Caustic, and fired it up. Only played around with it for 5 minutes yet, but it seems huge really. Wasn't expecting so much complexity tbh. It pleasantly reminds me of Reason btw. Need some more time with it though.
