I prefer my ereader, currently my favorite - a Kindle Paperwhite. The eInk is readable anywhere a book would be readable, and the Paperwhite's added adjustable frontlighting also lets me read in dim light and dark, so I can now read anywhere without needing to carry an extra light. I would not want to hold a bare plastic rectangle to read. I use a book-like cover (with a front cover I can fold all the way back).
I also really appreciate the ereader when I am reading a 700-1000+ page book. From experience I know it can be tiring to hold a huge physical book but on an ereader a 1000 page book adds no weight.
I get lots of new author and indie author ebooks for free - many have free promo days when new. I have hundreds of ebooks in my Kindle. And Amazon has a daily deal every day - 4 or more books (sometimes famous or bestseller) for $1.99 or $2.99 so I get some popular books that way. Amazon Kindle section has a Best Sellers list and you can choose Top 100 Free then choose categories at the left. I also use this site to find new/recent ebooks that are free at Amazon:

I'm in the US so I also plan to update my library card and get a pin - my local library supports Overdrive so I could borrow Kindle books at Overdrive (I think delivered/returned via Amazon).
My husband and I are voracious readers.and our townhouse is overflowing with books. We have bookshelves in every room except the bathrooms. Many are floor to ceiling and wall to wall with books stacked two deep. We had to stop buying physical books. We are in the process of donating our physical books to the library for their book sales. Some faves I replaced with the ebook version.
I do buy some books as physical books - any book with special binding or printing that's an integral part of the experience (for example the companion book to Stephen King's Rose Red was bound as a lady's journal, and the new JJ Abrams/Doug Dorst book S. has colored writing in the margins and loose enclosures between pages - I got those as physical). I also prefer physical for cookbooks, art/craft books. And I buy a used hardcover for a book I want to loan around to extended family.
