Overall the Amazon Kindle Oasis w/ Special Offers (WiFi)'s performance was excellent, among the best we've seen on all counts.
The 6-inch screen offers the best combination of display size, portability, and price for most buyers. Among the best we've seen, this monochrome screen has very crisp type. It's one of the best for reading in bright light like on a beach. It's one of the best for reading in low light as on an airplane or dimly lit room without needing a book light.
Responsiveness was excellent, among the best we've seen on all counts. It turns on almost instantly from sleep mode, and opens a book with practically no delay. Page turns are among the fastest we've seen, which should allow you to read without any pause for the page to refresh. Navigation was excellent, making this among the easiest models for getting around within a book. The screen periodically flashes to black during page turns, but the effect is brief and occurs only about every sixth page turn. The screen automatically re-orients images from portrait to landscape view when the device is turned. You can create your own bookmarks, and the last page you read is automatically saved. You can search through your entire library of books to find titles, which is convenient if you have a large collection of books stored on the reader. Purchased books are downloaded via a WiFi connection.
File support and versatility were very good, with a wide variety of common file formats supported and many convenient features among the models we've tested. You can purchase titles from the integrated Amazon ebook store. It supports Kindle AZW e-book format. The reader supports e-book loans from public libraries. You must use a computer to choose and download library books but the books are then transferred to the reader wirelessly. It has a touchscreen, which you can swipe or touch for easy page turns, but also includes page forward and back buttons as an alternative way to turn pages. Apps are available so you can read books on a PC, Mac, Blackberry device, Android device, iPhone, and Windows Phone in addition to the reader.
Among the useful features and attributes of this model are: Readability that's better than most other models we've tested, with crisp text and excellent contrast. WiFi connectivity for buying books and browsing the web.
Downsides: The battery is not user replaceable. A power supply or adapter is not included.
