I’ve been thinking about buying a Kindle DX ebook reader, given my addiction to books, both business and personal. On a recent flight from Boston I finally saw the larger DX model being used by my seatmate. A development manager for Microsoft, she uses hers on long flights to catch up on professional reading (long technical white papers, internal reports, etc.) and then relax with a favorite book. Her enthusiasm reawakened my interest in Kindle.
