A Kindle or Nook
These are ereaders. If you love to read as I do you will find these small, portable devices come in very handy. You can keep thousands of books on this one little device and it comes in so handy when sitting waiting to be loaded/unloaded, at truckstops. Try keeping tons of paperbacks in your cab where space is minimal and you'll discover the value of this little wonder. All you trucker bookworms will thank me!
