Yes, I have IQ on my milli. I had it on a 2007 model and traded up my machine, I think in 2014. I took it off the 2007, sold that machine and then put it on the new one (also upgraded to super motors). I love how easy it is to use. I don't use all of the capabilities because I don't do custom work. That is about to change because I want to do some custom on some tops that I have been saving. I took IQ to demo to some friends that had quilt path and they thought my system is easier to use. I can't say anything about quilt path because I have never used it.
