I find laptops (let alone phones) fairly unpleasant for anything resembling a comic. You really need a 4k monitor at least the size of a physical page. That usually implies portrait orientation, and then a second one for spreads, at which point just give up and use a large format tv. Or better yet just stick to paper.
I also have this problem with the scientific literature. Tablets let alone ereaders just don't cut it.
What I've long wished for but it doesn't seem to exist is a high resolution full color epaper tablet the size of a hardcover textbook page with a sub-second refresh time. Not live video or anything, 500 ms or so would be bearable for quickly panning around a document.
Indeed, and my kindle scribe 2022 10.3” 64 GB is bigger than a physical manga volume. I couldn’t imagine using anything smaller
Shrug. I've read comics on a 7" eReader, scientific papers on 7.8". Rarely is there a real problem IMO, occasionally color charts are a problem on my B&W reader.
I have slightly more sympathy for scientific papers due to smaller text and overall extra density but considering that it's pretty common for comic publishers themselves to release editions smaller than a typical 10.25x6.6 page, you don't really need page size (e.g., Archie's digests, every manga tankobon ever, DC Compact Comics).
