@ScarletBea has the right of it, as do others. Both. Here's an example.
For reading novels, it's almost always ebooks for me, for a somewhat odd reason. I read on my phone. The habit started while I was still working. I could steal a few minutes of reading time. A bookworm's version of a walk in the park.
But I'm also a historian and I have a couple hundred books (did a heartless harrowing a few years back) of scholarly works. I still consult them from time to time. Trust me, the quickest way to know what David Abulafia has to say about Emperor Otto's dealings with the Hohenstaufen is to scan. If all I wanted was the Battle of Bouvines, then sure, a search in an ebook probably does the job. But scanning an ebook is incredibly frustrating because it's so sloooow. Add to that my spatial memory--I can remember that a wanted passage was on the verso page about mid-way down--and the physical book still has it all over the ebook. Then add in something like Jansson's History of Art. Then add the wonderful fact of humans, who will perversely persist in doing as they please.
There's a place for physical books. At the same time, I find reading a novel in a physical book to be clumsy and annoying. And I gave up book sniffing years ago when I learned about archivist's lung. Just sort of lost the charm.
Both. Indisputably.
