Having a dedicated device with good reading UX affordances elevates the overall experience considerably.

I've primarily used a phone or a laptop prior to getting a tablet, but both provide a subpar experience for reading.

I've also had a Kindle for a while, but I found it frustrating to use for web and PDF content and so it mostly languished in my drawer.

Physical books have nice aesthetics, but overall unsatisfactory UX, so reading a print book is something that I'd do occasionally, but it requires additional effort/accommodation for the sake of the experience.
