I'll never give up physical books, or printed newspapers - I do read online as well but having an actual book in my hand and turning the pages is one of the greatest pleasures of life. And when a book is finished and finds a home on one of many bookshelves in the house it is there carrying all the memories that in invokes from the time of reading - I still have many of the books I read in my youth - I sincerely hope you don't ever regret letting your physical books go.
