Fortunately the delay on OT MKII gives me more time to absorb the manual and tutorial vids, giving me a more conceptual understanding of the how-to's, which will surely help to hit the ground running once it actually does arrive, at which point I'll have more brain energy to focus on the practical side of things.
A4 kinda worked this way. Being able to learn it conceptually first, and practically second helped me immensely to learn it with less frustration. I could see how trying to learn it all at once would slow a person down and hamper their understanding with concepts such as Kits and file hierarchy.
Horse first, cart second.
