I too used to be a VS addicted individual. When I bought my MacBook Pro I found I could still use VS (through Virtual Machine) running it better on the Mac than it ran on the PC based solution. I had experience with Eclipse though and one of the things that I liked with it was the ability to use the scripts of past. In fact that is one of the many real strengths in my opinion. So much so that I have made a concerted effort that future development will not happen in VS when and where ever possible.
