> I can't justify spending hundreds on InDesign
For what it's worth, not a single one of the Apple iWork User Guides (Keynote, Pages, Numbers) was made with Apple system level services and Apple application software. None. They were all made with Adobe application software that uses no Apple system level services, except the ICC profile database for the display profile.
With the analoguous argument I brought about that Apple made ColorSync useable for high resolution printing in 2002 by changing the Generic CMYK Profile, so by the same argument there is no Apple office anywhere that is in a position to use Apple application software for Apple advertising / documentation.
All I can do is write, and in writing I can tell the educational market what it should understand. If writing changes anything, then that's good. If it does not, then I have done what I could. Digitalisation is not going to go away, it is here to stay. So is bad advertising.
