Yes... what I finally do is, as you say, convert everything to PNG to work in iPad. My preferred iPad illustration tool is Procreate, it’s a painting program without vectors, but with grid, perspective, isometric and guide aid tools that we could only dream in Illustrator. So everytime I want to draw ideas, paint an illustration, or sketch a logo, I import these PNG’s and use it as template to draw and add elements. Later I can export these modified PNG's again to Illustrator to use as a template to create the definitive vector work. Anyway, as inspiration happens everywhere, sometimes I would like I had an Adobe app right in iPad, with which I could at least, convert an AI file to a rasterized format (maybe some kind of Acrobar rendering engine, used to rasterize PDF’s). Right now, I need to wait to get an Illustrator near, to convert these files. And about filesystem… I’m like you, I’ve grown with the old folder hierarchy tree philosophy, so I need to use always a tree logic system to manage my projects, ideas and assets. In iPad, managing files from different cloud drives is still a nightmare and counterintuitive. For example, in the aforementioned Procreate app, you have to click many times to find the route to your images, because the program doesn’t let you navigate upwards in the file tree, so if you have to add another image in a upper level, you can only go back to the root folder and start do dig again in the branches. Definitively, iPad isn’t (still) a computer replacement… it’s simply a fast and powerful tablet with tons of creative tools, perfect for cooperate with their big desktop brothers.
