I use 'briss' to trim PDF margins from a laptop, then send to a Kobo Forma (8-inch 4x3 screen) and read using the open source 'koreader', which also works with Remarkable. I was reading on an iPad mini before (same exact screen size), but that's collecting dust now. I expect with the Remarkable's 10.3-inch display you wouldn't even need to trim margins.

Yes - but my interest is in the UX responsiveness, the whole point of the bigger screen size is to fit them on without stuff like Briss (which I've used before); the issue is not screen fit, but performance when browsing back and forth - tech manuals are not linear reads like novels, for which kindles etc are ideal.
