I have not purchased a Pi yet, but am considering, but need to know a few things before I do so.
A few things I would like to know:
1) Do all of your codes and Scratch files etc. save to the sd card with the OS on it (probably NOOBS installer in my case)
2) Can you be using different OS's for different projects, or would you need different SD cards for this, and you would have to probably reformat the Pi wouldn't you if you do this?
I think that is all I need to know for now, but I will tell you all if there is anything else I need
