There's another important environment that Unity 2D supported: VMs which lack
OpenGL support. An example of this is VMware Fusion on OS X which, until
recently did not support Unity 3D. I believe it still does not *officially*
support OpenGL on non-Windows guests.
Unofficially though, at least with 12.10 (and I think 12.04), Fusion 4.1 does
support OpenGL sufficiently to allow you to run Unity 3D. Go to the
Settings->Display page and enable Accelerate 3D Graphics (shut down your VM
first).
I've been running 12.10 this way since early pre-alphas and it seems to work
fairly well, with minimal glitches. The most noticeable for me is that Emacs
repaints rather slowly from top to bottom on some full refreshes. I don't see
this on native hardware.
Other than a few other weird little issues that show up only on Unity 3D[*],
I've been generally happy about it lately on a variety of real and virtual
hardware.
