Agreed. I scanned a short book with my phone, and a dedicated scanner would have been nice to have.
But with page flattening and separation and automated capture, it went much faster than I would have thought. If I were going to do a lot more, I'd want something like a scan tent [1]. It's not as ergonomic as a dedicated solution, but in 2026 a phone and some light can get you a lot of the way there, pretty fast.
