I had an opportunity recently to test drive several eBook devices and I would like to provide you my personal review on them, and how they may affect a visually impaired person. I am only going to review 4 of the most popular devices in this article. More units are coming on the market every week.
Warning: Your needs and desires may be different, so please do the investigation to see what will be best for you before purchasing.
Barnes and Noble Nook and Nook Color
Barnes and Noble has come out with 2 units that are an eReader. As the description states one is a Color unit and the other is just a gray scale unit. The plain Nook has a small area that is used for navigation. On the other hand, the Nook Color uses the full screen for navigation. As far as the menus are concerned on both devices, you cannot adjust the font size for the menus. You can however adjust the font size in the eBooks. The screen size for the Nook is 6”, and Nook Color is 7”. Some units require a contract with a cellular carrier. Barnes and Noble does offer a Wi-Fi only model, which will still allow you to use this device wirelessly. You can listen to music and audio books on these devices, but only with a headphone, no external speakers. You are limited to only purchasing books from Barnes and Noble. Nook can be read in direct sun light, but cannot be read in the dark. Nook Color is the opposite, you cannot read it in direct sun light, however can be read in the dark. The Nook Color can also read magazines and newspapers. The Nook uses E-Ink technology, and Color Nook does not. Supported file formats are: PDF, ePub, JPEG, PNG, GIF, BMP, PDB and MP3. Does have an expandable memory slot. Price point varies from $150 – $250.
Amazon Kindle and Kindle DX
Amazon has come out with 2 units that are an eReader. The only major difference between these 2 is screen size. Kindle screen is 6” diagonally. Kindle DX is 9.7” diagonally. Both units have an external keyboard for navigation. The type on each letter is very tiny to see, memorization would be required to use them successfully. You can however adjust the font size in the eBooks. The screens are not touchscreen. Amazon, does have an experimental feature on some models that will actually read the book to you, however some publishers of books are opting out of that feature. These units do have an external speaker as well as a port for headphones. You are limited to only purchasing books from Amazon. Kindle and Kindle DX can be read in direct sun light, but cannot be read in the dark, due to E-Ink technology. They both have Wi-Fi, and some units require a contract with a cellular provider to access content. These units are just for eBooks and nothing more. Price point varies from $150 – $380.
Sony Pocket and Daily Edition eReader
Sony has come out with 2 units that are an eReader. The only major difference between these 2 is screen size. Pocket screen is 6” diagonally. Daily is 7” diagonally. Both units are completely touchscreen. You can adjust the font size in the eBooks. They both have expandable memory. They both have Wi-Fi, and some units require a contract with a cellular provider to access content. Sony units can be read in direct sun light, but cannot be read in the dark, due to E-Ink technology. These units are just for eBooks and nothing more. You can listen to music on both units through headphones. Supports ePub, PDF, BBeB Book, text, RTF, JPEG, PNG, GIF, BMP and MP3 formats. Price point varies from $180 – $300.
Apple iPad and iPad 2
Apple has come out with the iPad units that are more than just an eReader, they are tablets. The term tablet means that it is a multipurpose unit beyond an eReader but not a full functioning laptop. The iPad and iPad 2 are just slightly different. I will not go in to the differences here, because they do not affect the reading of eBooks. To make this easy, I will just say iPad in this article. iPad has a 9.7” screen. It is a full size touchscreen. Apple has an accessibility section that would need to be setup, to allow you to zoom from 1x to a 5x anywhere you may be on the device. This feature does require some practice, and the use of 3 fingers. In addition, it has text-to-speech feature. You can click an item and it will read it aloud for you. They do have an external speaker as well as a jack for headphones. The devices can be used for a multitude of things, such as watch movies, surf the web, write email, and the list goes on. You can set some fonts to a larger size, just depending on the application you are in. The nice feature of this is you can read books from Amazon, Barnes and Noble, and any other source. They do not have expandable memory at this time. They both have Wi-Fi, and some units require a contract with a cellular provider to access content. iPad units cannot be read in direct sun light, but can be read in the dark. Price point varies from $500 – $830.
As you can tell from this review, options vary greatly. The 3 genuine eReaders listed here do use what is called E-Ink technology, which may be better on your eyes.
This is a personal decision, however if I want just an eReader, I would choose Kindle DX for the screen size. The larger the screen the more text you can have on the screen at one time, and so far seems the best for a visually impaired reader. On the other hand, if I had the money, I would choose the iPad, because it does allow you to zoom in farther then the largest font size available. In addition, it has so many other options and applications that it would be a great multipurpose device without carrying around heavy laptop.
I hope this helps you in making an informed decision.
