If you have an ereader with an eink screen... it's a no-brainer. Digital books are soooo good.

• virtually no weight
• virtually no space
• waaaaay cheaper
• your local library has probably a way bigger and more accessible catalogue of ebooks than physical ones
• tap and hold a word and get an automatic definition/translation
• adjust text size or font
• dark mode, if you into that (in some models)
• Text-to-speech (in some models)
• highlight text and write notes without f-ing up pages
• literally translate entire phrases or look particular information from Wikipedia or similar with a simple gesture.
• backup all of those and do crazy stuff like an automatic daily email to yourself with cool notes you took months/years ago.

Physical books nowadays are like vynil music... it's for the artwork and having a physical "certificate" of something you love. Like... if I discover a book I really enjoy, I'll probably buy a physical version so I can, you know, have it there on the shelf, like you have family pics or something.
