My limited experience with graphical programming is that of using LabView for a test set that a customer requested, rather than my usual programming language of choice. I am not a big fan of graphical programming although I know a lot of folks are - I do get concerned because I think that "you can focus on engineering/design concepts, instead of teaching a programming language" may be a good start for getting young people interested - but if you don't learn a programming language, you sacrifice the ability to have low level control when you need it.
