I've done some searching but come up empty handed. Anyone know of (or better still 'use') any textbook which is NOT MS/Windows based? So many textbooks seem to only cater to teaching kids the MS Office suite and Windows-based OS. I know there must be SOME schools out there who have gone down the open-source/Linux/Ubuntu route - if you know of them and could put me in touch that would be great! I'm in a Ubuntu-based environment and short of creating the materials myself (which is a big task from Year 1 upwards!) I was hoping there was at least one other option. Cheers.
