I don't miss it, because I do both. I like the Kindle app, which I use on my ipad mini. My mother and I share the account and we read a lot of the same books, so it is nice to be able to share stuff that way. Our public library has a pretty good selection of Kindle books, and I can also read and listen using the Overdrive app. Another nice thing; I like to knit, and can knit and read at the same time when using the Kindle app.
That said, I still occasionally read print books. If the library only has a hard copy, that is fine. Or like now, when I am about to out on our dock (I'm at the lake cabin), don't want to worry about electronics falling in the water, LOL.
