While I also rarely purchase paper anymore, individual anecdotes do not necessarily reflect or predict the actions of millions of people.
For example, ebooks are still a fairly small part of book sales -- 5% or so. Even with the recent explosive growth in ebooks, it's going to be a long time before it reaches parity with paper books.
Paper is still superior for many roles: Library use, art books, text books, nearly anything that needs to be marked up. It is also possible that as the industry does more and more digital versions, they may be able to make more books available in a print-on-demand format. On-site POD equipment may also drop in price enough to justify their use in small stores.
Also, for all the attention on digital, physical CD sales still make up the lion's share of sales and revenues. In 2009, CD's made up 80% of album sales, and digital was around 25% of total revenues. The overall CD sales declines, plus an increase in online purchases of CD's, have gotten to the point where retail outlets are getting killed -- but physical sales still continue and make up the majority of revenues.
Old habits die hard; and media attention and/or web forums do not necessarily reflect the economic realities.
