I have to say that I am quite excited about the possibilty of using an iPad to control my equipment. It seems like the answer I have been looking for. It's not something I can afford at the moment, but I'm very interested to hear about other people's experience. I was wondering how in-depth it is to create a decent interface with one of the various Apps available? Am I correct in guessing that these Apps will not allow for real time feedback from devices?
