“Well, they do, but the reading kindles are very slow and the graphics virtually non-existent.”
I don’t use those even though someone suggested I get one. I prefer books and my house is full of them.
No graphics? Sounds like that would suck for the Science teachers at school? Wonder how that fares out?
Kindle fires are color, so, again, if the textbooks are formatted for kindle the graphics would be good.
I have about 900 kindle books. My house was full of books - and I was a regular library visitor - then my grown children bought me a kindle and after a "learning" period, it is my primary reader now. I can even adjust the type size (old eyes) and I cannot do that with a book.
