The school I am teaching in is considering getting Raspberry Pi computers. As programming will get bundled into all school subjects, there is a need for small programmable computers with GPIO in order to boost the pupils creativity.

I am going to suggest to get Raspberry Pi 2 B for development of a product. Once the development is ready, one can make it into a ready product by replacing Pi 2 B with Pi Zero, and it is something cheap enough that the pupils could even get it home.

For example, if one wants to make an "extension cord" with a box turning on and off the current when you clap your hands, the Pi Zero would get mounted inside of that box, making the product cheaper. The development itself would be on a Pi 2 B as it is strong enough to keep both an IDE and a browser open for reading documentation, allowing the pupil to do the whole development directly on a real Pi.
