Probably also to appear more modern. The problem with that approach is that, besides well known touch screens usability issues, it takes only one bump in the wrong spot to screw all the interface, so it's cheaper only until something goes wrong. They seem to know this though, as Space-X ships have all important functions replicated on real physical interfaces.
SpaceX did it on the Dragon too. Hard to imagine an environment that is more mission critical and less cost sensitive than a space ship under severe engine vibration or tumbling out of control though space.
I think that's different though. Spacecraft have orders of magnitude more features that need to be controlled than cars do. Just look at how busy the space shuttle cockpit was.
