Guys, check out this app, it has returned my workflow to all its Snow Leopard glory. Total Spaces http://totalspaces.binaryage.com/ I'm in no way affiliated with Total Spaces. Just glad to have this functionality back! If you do download it, you may want to assign the keyboard shortcut to go to the overview grid to a trackpad gesture using BetterTouchTool. Then you can access the overview grid as well as swipe between spaces using the track pad.
