I upgraded recently from v9. Latest version works better with Win7 64 bit, but apart from that it has no new features that I use. My requirements are quite basic, usually involving audio and it is fine for that, but I probably only touch 10% of the functionality.
The 3D glasses are cheap and nasty paper ones, but they did seem to work on the one occasion that I tried them out.
If it wasn't for W7 compatibility, I would consider it money wasted to upgrade.
