Introduction to LightSwitch

LightSwicth is a new development tool by Microsoft, targeting power-users and non-professional developers, willing to write data-oriented business applications.
LightSwitch can bee seen as a kind of "VB / Access for the Cloud".
The tool is quite complete and easy to use by default but it also provides a lot of customization features.
Here is a good introduction video:

It is currently in Beta2 stage, but it is stable enough to be seriously evaluated.
