In the upcoming Ubuntu 12.10 - Unity 2D will be removed. Thanks to LLVMpipe, a computer that isn't capable of running Unity 3D is getting the same experience without the Compiz effects.

But what if I don't want Unity 3D at all? I have a Dell Inspiron 1525 that's capable to run Unity 3D, yet it's slow. Very slow. Unity 2D, however, is faster. How do I enjoy the snappiness of 2D from 12.10?

You can look at Unity going forward for an idea on the current understanding of how older machines may cope.

As I mentioned, this approach is a work in progress as we tweak the experience and effects to maximize the performance. We expect this to shake out over the rest of this cycle and bleed into 13.04 as well. ... Still, with all the above, there will be systems that are simply too old to run Unity. In those cases it would be necessary to either stick with 12.04 LTS or run another desktop environment.

"Older machines"... How about "People who don't want the buggy POS that's called Compiz"? – Lennart Regebro Oct 20 '12 at 12:04
