Well, the National Instruments page pretty well answers the question what LabView does. Also, most institutions using LabView have Academic site licenses, where a Student Edition costs $20 or so. This is also quite well described on the National Instruments page. So all in all, having a look what National Instruments has to say about Labview isn't so unreasonable, is it?
Of course it's not 
I just hoped for someone who has used the program tell me his thoughts, his experience, whatever. Of course I googled it but I wanted someone of the "Arduino people", whom I have a common knowledge base with.
Also, it's not only about the cost, it's about using propietary software. I really hate to have to and avoid it every time I can.
From what I've understood so far the only "good" thing about LabView is it's graphical, it has a great interface and lots of toolkits that make life easier - especially for someone who's not interested in coding, but in interfacing easily with hardware. But, apart from this user-friendliness, all could be done in puredata or supercollider (which have allready some built-in code for comunicating with external devices) or straight C.
Am I more or less correct?
