Well first and most important my habits have changed from not reading at all anymore to being able to again. My first ebooks I read with my first kindle in 2008. My eyes could not handle the small font anymore and my hands hurt with paperbacks. And the smell of some of the old used books.
I also have one bookshelf only now for space. I used to borrow a lot of paper books before and bought and resold to not keep to much in the house.
I read much more now, its just easier on e-ink for my eyes. Its easier to follow series now.
And one of the most happy things I found was back list. In the genre I most like to read the 90's and early 2000's were haydays of some of the best of books. Yet, many were out of print and often with a very high price for a nasty old books. I am so happy to see a lot of this backlist being out there for me to read finally. Or again.
I been able to read and find more books in the genres/subgenres I like now with ebooks. Partly of course because of all the social media and online readers that have also embraced ebooks.
I read about twice a fast on e-ink compared to paperback, so I can now read twice as many books in a year. Win win
