To be fair, eBooks have just gotten that big in recent years because the publishers are lazy and cram uncompressed embedded fonts into them.

I always strip out embedded fonts from my eBooks with calibre and I have seen books being reduced from 20MB to 400KB. 🤣

This won't make this a good device due to a myriad of other reasons, though.
