@Calin:LightSwitch apps are easy to build and easy to deploy locally. The same is true of a number of other tools, including Access and Excel. One key way LightSwitch differs from other easy to use tools is that the apps are ready to be deployed to IIS and Azure. If I build an expense reporting app in LightSwitch for my team and then the entire company wants to use it, I can deploy it company wide without having to rewrite anything. All I have to do is make sure the IIS server is ready for LightSwitch and then run the Publish Wizard. Bingo. I think that does a good job of addressing that source of "haunting".
