I am considering purchasing an e-reader. I am currently leaning toward the Kindle, but am also considering the Nook and the iPad. In addition to novels and casebooks, I'm also hoping to use the device to read law review articles and Federal Circuit patent decisions that are currently in PDF format. Why?: I am looking for a lightweight dedicated reading device to help me avoid distractions and weight of my Thinkpad. I am also enamored by the e-ink and have the idea that it would help reduce eye strain.
Any advice before purchasing? Is 3G valuable? Is there an easy way to access the newest Federal Circuit patent decisions on the Kindle or Nook (or should Patently-O begin offering that service?)
