Another ebook has hit the market named the COOL-ER that uses E-InkR. This new technology produces a paperlike display that is meant to make you feel more like you are reading a book. Power is only used for “page turning,” so a single charge is good for up to 8,000 pages. The COOL-ER lets you change the text size, has PDF support and an SD card reader, all at a price of $249.00. Less expensive initially, downloads may cost you more than those for the Kindle.
