Update: Discontinued in September 2012 by Amazon, the model was replaced by a new E-Ink ereader called Kindle Paperwhite.
The Kindle Touch has a touch-screen interface and can store about 3,500 books. The E-Ink display makes it easy to read in bright sunlight. Because the E-Ink does not drain the battery as quickly as full-color screens, it is capable of working on a single charge for up to two months.
The Kindle Touch is capable of reading PDFs, Word documents and text files. It also can play MP3 files and read books aloud. It provides access to more than 800,000 books that cost less than $10, and there are millions more books published prior to 1923 that are free.
The "Special Offers" version is available at a discounted price because of ad support. The ads only show up on the home screen and while not in use; they do not interfere with the reading experience.
CostHelper Bottom Line: The Kindle Touch is no longer available through retailers or the manufacturer, but can still be purchased through online auction sites. The auctions often end well below the original MSRP of $99 or $139 for Wi-Fi models and $149 or $189 for 3G models. Typically, auction buyers paid $60-$80 for Kindle Touch models.
