I miss going into the bookstore, but I've still got literally stacks of paper books that are waiting to be read (in addition to all my ebooks) and I physically don't have any more room to store books. So that's the main reason why I've curtailed my visits to actual book stores - I have no place to put them (and God forbid I should throw out or sell a book to actually make some space
).
I think that if I had more storage space, I would still be buying paper books close to the rate that I was before, though I might be picking up more tomes that just don't display right on a 6" ereader. I still get some paper books each month to review; those are currently stacked on my coffee table.
