I have allowed the apple train of progress to run me over and installed Mountain Lion. It was a welcome surprise that it installed without issue and runs smoothly. However the downgrade of mission control still sucks, but I shall be keeping an eye on this for hope :

I think apple probably knows that mission control doesn't really do the job. Hopefully they will shake things up again in the next incarnation of OSX and make something better. If mission control is mobileMe I'm looking forward to iCloud
