I've just been having a read through this, mainly the OS choice at the moment.
Some OS's for me to have a look at, the camera one seems interesting.
Noticed one error, oddly for Raspian.
You say there is no graphical manger installing but there is.
Hang on I've just check online and it different, it also seems to have quite a few more OSs covered than my print version (unless i was sleeping?)
It jumped from Raspian to something like osmc/ RetroPie.
Some 3 or 4 more pages?
Am i dreaming or is there a big error in the print sent out?
