My e-reader is an old Sony I got off eBay, and until very recently, I only used it to catch up on public domain classics. I actually purchased my very first e-book just the other week. (It's by another old buddy of ours, Eli Pariser, called The Filter Bubble, is about how personalization on the Web restricts rather than expands the information we have access to, and has been pimped in a previous edition of my column.)
