I would say having to have every game installed allows for developers to take advantage of that. Being able to play disc games without having the disc in the tray (so the benefits of digital) being able to play your entire X1 library on any X1. Background downloads/install/updates also.
PS4 has more advantages over X1 obviously, but there are some X1 has that have come out of this DRM .. thing.
As far as the cloud enhancing games, I'll believe it when I see it and when Microsoft talks more about it.
Edit: X1 also has a poweful company with deep pockets behind it :P
