Hello folks, I'm late at listening and this is somewhat off topic but I just can't keep my mouth shut. Sorry for that.
I coughed on the bit "Beamer is obviously the German word for projector." You are virtually right and even the "Duden", as sort of a reference for the German language, backs "Beamer". However, I still don't want to call it a "German word". It is an English word, or derived from it, that is used by Germans. There is the matching word "Projektor" in German, just no one is using it to reference to a data projector. 
Alas, it is so common these days to call things by, what some people think might be, the English term for it. Just because it is supposed to be cool. An other great example of this is the use of the term "public viewing" in German to reference to watching a sports event on a giant screen in a public place like a town square.
