What about latency?
The writing latency isn't bad at all. It honestly feels like writing on paper with a really good pen. Latency is noticeable if you're actively looking for it, but it doesn't affect writing at all.
The quality though isn't ideal. All of the Remarkable devices have terrible issues with screen calibration, so the line you're writing doesn't match where the stylus is. Also lines tend to be jagged or fuzzy.
