It is the same hidden cost of the cRIO especially back 3 or more years ago when the 8 slot cRIO was the FIRST approved system.

How many of these do you have knocking around to develop on?

Think about it: general purpose laptops are plentiful and therefore anyone with a laptop (increasingly all the students in a school) could snag a USB camera for <$30 and start writing vision code. If you are using old phones you can get the whole package probably for $100 or less and probably your students are already glued to the phones they use too often every day now.

On the other hand if you buy a development board for nearly $200 how many people can actively develop/test on it?
If a student takes that board home how many other students can work and be confident that what they are doing will port to that system?
Vision is a big project and more importantly you can often play a FIRST game without it.

Is it better to use laptops you probably already have or commit to more proprietary stuff you might have to buy multiple of and then....if that product goes out of production...do that all over again if you even really use it? Is the cost justifiable?
Not necessarily. Most people use open cv libraries with c++ on the Jetson TK1, and other SBLC's. The libraries are written the same for it, Linux pc's, laptops, windows pc's, etc. Even the GPU libraries are fuctionaly the same and look almost identical. Furthermore standard open cv GPU libraries work with Nividia GPU's in general not just the Jetson. If you mean Linux vs windows... before the Jetson I've never used Linux but the GUI desktop is very easy to get into and I was able to install everything necessary having never used linux. Thus anyone with a computer or other SBLC running windows/Linux and able to dev in C++ can write code that can be used on the co-processor.
