I've been telling everyone who asks my opinion of the various e-readers available. One of the main points in favor of the Kindle is that Amazon has a reputation for quality customer service. This weekend I experienced it for myself! On Thursday late afternoon my Kindle froze up when I tried to wake it. I was on the phone with a Kindle customer service representative within minutes thanks to Amazon's call me back feature.
By Saturday I had a new Kindle in my hands and a prepaid mailing label to send back the other one.
Absolutely the best!
