I've moved my computer way too often to give a single damn about cable management! Even less so with the Xbox and the Logitech speaker cables coming out of that sub.
iControl is fine, the only real issue is the two-finger swipe to get to, say, the radio stack. You can too easily hit one of the buttons on the UFC... but that's just a matter of hitting C to clear the screen. As far as immersiveness though, my head is twisting with the trackIR, feet are in motion, both hands on the HOTAS and manipulating the primary control panels via the iPad... it feels like freedom!
