For me it's about the content, not about the delivery system. Even though I do prefer reading electronically over reading paper books, I have no problem reading a paper book. When I'm looking for a particular book to read I always check the Phoenix Online Digital Library for the Kindle book first, then I check my brick-and-mortar library if the Kindle book isn't available. If it's not available at either place then chances are I'm not going to read it.
I will admit that I do seem to have a weakness for the clearance racks at Half Price Books...
