I got a remarkable way back in grad school when it was the only real option for full size reader that could handle PDFs so I could use it to read and annotate scientific papers which don’t handle conversion well. Now there’s a bunch of products that can do it. But for the remarkable 1 at least, you upload books into the remarkable app and it’ll auto download onto the device over wifi, so no need to plug it in. However, everything goes through the remarkable server so defeats the underlying principles of self hosting lol
