Smaller stores inside more downtown areas with more emphasis on the cafe, free wi-fi, print-on-site books, and ebooks.
Huge mega stores in malls full of 40 dollar books is a sure loser.
A combo of Panera Bread & Barnes and Noble would work for me. I had a kindle, now I have a nook tablet. Very happy with both. I believe we still need real books for children. I cannot see buying them a kindle or nook.
