Thats just how > "commidity" these items are in the educational world. Secondary schools in NZ (ages 13-17) use RPi platforms as their introduction to maker-systems. While there are better boards available, RPi platforms are easier for the general public to obtain. Having good support on the RPi is crucial for introducing beginners to FreeBSD. As it is, Linux is currently the preferred O/S due to better support on RPI3. Just my 2-cents. -- Jonathan Chen
