It is very worth while knowing what tools are avaiable. Say for example one of your support tech needs to do something simple like query a database and write a list of outstanding calls to a web page, what you going to suggest? Add it to our backlog, we'll get to it in two years. Here's a copy of VS2010, good luck. Or here is a simple tool, you can install in 5 that will pretty much guide you through the process and has a lot of template examples?
Just because your not going to use it, doesn't me you shouldn't know what exists. Same goes for Lightswitch.
