Definition: Given an Amazon customer review, write a title for the review. The preferred titles are under fifteen words.
Input: Whatever eReader you decide on, consider there are two minimum qualifications: a large catalog and eInk. The first is obvious. Why buy an eReader without easy access to any book that you can pick up at a large book retailer? The second must not be discounted. If you purchase an eReader with a backlight, your eyes will tire after a chapter or two and I fear will have hazardous effects for heavy readers.<br /><br />The reason I give the Kindle 5 stars is that it is one of two eReaders (including eReader software) that meets this criterion. Naysayers will rightly so complain about wiz-bang design issues in the Kindle. But, unless a device meets these two qualifications, it is not an eReader.

Why 5 and not 4 stars?
