This is especially handy if I'm navigating new places, where I can get the map right there in front of me. No need to look to the side, so can keep my eyes on the road more.
That said I think Renault has struck a nice balance between digital and physical. AC controls are physical, as is volume/mute and a few more.
All the physical buttons are still available via voice commands, which I also like. If a lot is happening on the road it's sometimes better to be able to keep both eyes on the road and hands on the wheel.
And as much as I dislike touch, at least it works well and the hardware driving the screens is snappy and responsive, like a good tablet.
