What Would You Like to See in a OS?

I've been thinking about this for a while, the dream OS. One that converges stability, compatiblity (backwards and forwards), security, looks and extendiblity. It would probably have to originate from the UNIX vein and be able to do all of the same things reguardless of the platform it's on (i386, 64-bit, Power PC).

One of the big needs would be the ablity to run all Windows NT (NT 3.1-XP), Windows 9x, DOS 1-6.22 + Windows 1-3x, Mac OS Classic and OS X, Linux programs. With this you could potentially run millions of programs past, present and future.

The other need would be a 3D GUI (with a 2D or command-line GUI as well). Since Vista will be needing DirectX 9, why can't it pull a full polygonal interface? It wouldn't take too much 3D power; and execution would be like Homeworld (the PC game), the perfect example to use. Imagine being able not to just scroll, but roatate and pan around? It would be really powerful and very nice to use.

Alas, no one would be able to pull all of this together, it'd take the combined pooling of all the current OSes source codes to be released to even come close. But there's always potential for it to happen.
