I get the same message. I believe that you have to be attending college or some post secondary school to purchase this item. I purchased some items in the past and had to prove that I was attending college.
I was considering that this may be an easy way into learning LabView and creating test jigs (as mention in my upcoming blog The ART of Test, part 3). I don't mind that it is aimed at students and a structured learning experience may be just what the doctor ordered.
I tried the website and I am unable to find a price for the development kit. It seems to want a part number and when I try and plug in "NI myRIO-1900" (or even "myRIO-1900", one of the parts with WiFi) it is unrecognized. I cannot find an equivalence to another NI part, and I quickly tired of the search. I do prefer it when I don't have to strain to get information. There is probably a simple link- I am just not seeing it.
I guess I will try to pin it down at EE Live (they have always been there so I hope they will be again).
