Some general tips for OS X (subjective of course)
- Spaces are akin to Workspaces (Three finger left/right swipe) and are great for running VM's fullscreen.
- Use gestures (Two finger/Three finger Left/Right/Up/Down swipe or grab/spread)
- Spotlight (Command-Space) is handy
- Give Safari a fair try but you mightn't like it (I switched from Chrome last year and am loving it)
- I never use Launchpad (Grab gesture)
