's just the same with Parallels... I've bought v6 which isn't compatible with Mountain Lion now (worked with Lion just fine)

Faced with the decision to shell out 50€ to make it run with a 16€ OS upgrade after a little thinking, googling etc. i just went with Bootcamp & Windows 7.

While this doesn't have the convenience of just starting the VM (gotta reboot) it at least has native performance which in my use-case (3D CAD) is more desirable anyways.

And you can't beat the feeling of not being extorted anymore...
