This is one of the "wish list" items I have. There are numerous interfaces out there but the one I find I like the most is the Alesis iO Dock because of it seemingly self contained portability. Although the Focusrite might appear to have a few better options over the Alesis. My goal is to minimize the tangle of connections by adding additional components and then the inputs to them. I Have come to believe though that product development is a little behind in this arena and once I make a decision, THAT'S when the next generation will show up.
My need to keep it self contained is so strong that it keeps me from moving forward with this purchase or I would have decided on the Focusrite a month ago.
Good luck with your decision
