The suits are just pressure suits, more for basic protection and temporary loss of pressure, not extended EVAs or anything. They do look pretty comfortable, though, and I think the audio and signal are better.

The touchscreen interface is "different" - the astronauts talked a bit about helping SpaceX design it and the pros and cons of it in a recent interview. I wrote it up here but you can also check the original long NASA TV thing.

I watched the "Everyday Astronaut" Youtube stream where he said that those are IVA suits (as opposed to EVA) and can only hold pressure for a couple of minutes, enough time for the capsule to return safely to earth in case of an emergency.
