Inventor Spot has a special holiday comparison between the Kindle, Nook, and Sony e-Reader. Here are the highlights of Kindle vs Nook vs Sony:
Sony: While Sony will link its products to its vast library of digital content, the biggest difference with Amazon and Barnes & Noble is that in addition to selling product, according to a Money Times report at Sony’s online service will permit visitors to tap into their preference for social networking by allowing them to create an account where they can upload their videos, photos and other digital content.
Nook: Barnes and Noble experiencing similar issues says that pre-orders of its stylish new Nook e-Reader have exceeded expectations and the company has sold out its initial supply. Anyone promising a friend or loved one a Nook for Christmas will have to provide them with a gift certificate and an apology. Barnes & Noble says the earliest that customers will receive their devices is January 4.
Kindle: Amazon had similar problems in previous years but now appears to have figured out how to meet the demand for Christmas 2009. That leaves the Kindle as the most prominent wireless e-Reader available for the holidays, although Sony is still selling two non-wireless Readers, The Pocket and The Touch, which must be plugged into PCs to download books.
