Touchscreen is a must have for the nav unit, specifically for browsing the map with the pinch zoom and drag panning. Multi-purpose programmable physical buttons are nice in theory but in practice they suck donkeys balls if you pardon my French. Inconvenient and more importantly they make the UI feel unfinished and temporary. Should they have customizable labels similar to those of the Optimus keyboard - that would've solved the problem, but at what cost. With regards to a good voice recognition - the current generation on BMWs is really good, especially compared to the one from two years ago that was bloody awful. One thing that I do miss from the handsfree system is an ability to use different voice packs. It'd be super cool to have a dude with a heavy Indian accent :)
