It is perfectly serviceable for reading, though it may lack some of the reading oriented features of other eink devices. I love the large size for some of my documents, which are unpleasant to read on smaller devices.

What you re missing?

Based on other comments here, it seems that the Remarkable is missing several features that some people enjoy in their eReaders. The only one I can cite definitively is the lack of backlight. I can't speak to other allegedly missing features because I haven't investigated the issue. I am satisfied with the features I do use when I want to read certain docs on the large remarkable screen.

I don't think it's that great for reading. It does not have a backlight. I own both the reMarkable and Kindle Paperwhite and I prefer to read books on the Kindle.

It is suitable for reading PDFs, but don't expect much. It doesn't have a web browser and doesn't run Android apps.
