Well, I discussed the matter with a colleague (having in mind the offer when buying to machines) and he pointed out something:
For academic purposes it is useful to have more than one documents (and often the browser) open. If I am not mistaken, M92 can only have one document or the browser open at any moment. The only 9.7'' e-reader that can do this is PocketBook Pro 912, although I do not know the exact effectiveness in practice (how easy and fast it is to switch between open documents).
So this is a very essential question we have for M92. Can someone clarify this point?
Thank you in advance.
