Funny thing about exsisting OS interfaces. They were built around keyboard and mouse input so MT seems overkill.
It’s not, it’s just that the OS isn’t built for that kind of interface.
I think MT deserves an OS of it’s very own. One that fully utilizes the capabilities of MT.
I see an OS where storage space will be a 3D environment, 3D photo and video editing will be standard tools.
How about a 3D browser looking at the entire internet as a mesh that can be moved through with every link visible and traceable.
All these demos show us the eyecandy and proof of concept. I think it’s communities like NUI that will help foster developement of real world applications of MT and maybe one day an OS built around it.
