Hello, I am building a home studio (music composition, arranging, recording, etc.) and I am wondering about the use of a forthcoming Imac instead of a MacPro. All studios seem to use a MacPro, but I don't understand the reasons for such a choice. Current processors can run ProTools with as many tracks as needed, so what are the pros and cons of Imac versus MacPro, the possible bottlenecks of Imacs, etc. ? Thanks for your comments and suggestions !
