We have Kindle Paperwhites. No one is disturbed if late night/in the night reading is needed. We also have the App on our iPads.
The light is excellent and the type can be adjusted for comfortable reading.
Bought - with much relief - when we were regularly going to our holiday home in Greece and we sometimes had 24 plus books in the car....dragging all of them across Europe. That’s also some weight. Unless you are easily able to give away or pass on your books, what happens when your home just won’t store any more?
A book - the feel, the look, memories, will never be replaced by a Kindle. I can, for example, access any recipe I could ever need from my tablet, but cannot compare all that instant efficiency with the pleasure of sitting in my kitchen going back and forth through favourite cookery books.
However, being able to easily carry a veritable library on your Kindle, maybe in a handbag or keeping the one slim case beside your bed, in the bar, in the garden. Nothing to beat that. Buy one, you won’t regret it.
