The Sony PRS is one of the strongest competitors to the Amazon Kindle. Launched a few weeks after the Kindle, Sony e-book reader SOA is rapidly gaining ground in sales and popularity. Both e-book reader share the same basic functions. The biggest difference in the properties of the Amazon Kindle and the Sony PRS-505 is the price, design, usability and readability. A major difference is the price for these two models. Kindle costs about $ 100 more than the Sony model. The Kindle has additional features to justify the premium hard? The main difference between Amazon’s Kindle and other e-book reader Amazon, SOA’s Whispernet wireless connectivity. It uses the mobile phone, 3G technology, SOA, so the Amazon e-book store where you are. The Sony PRS-505 uses the other normal wireless WI-FI. You may not have access to Sony E-Book Store AOS if the Internet connection. Is the enhanced functionality provides an additional $ 100? You be the judge. Another reader difference between these two e-book is the design. The Amazon Kindle has a glossy white enclosure with a minimalist design. The Sony PRS-505 compared to the other in a metallic silver exterior that is more stylish and thin, the Kindle. Many comments are Sony, the AA model as a higher, Äòcool factor, AO compared to other models. Personally I think one of the best features of the Sony PRS-505, his kindness. The user interface is simple and incredibly easy to use. Once connected to the PC, you can have more than a dozen e-books in less than 2 minutes. There are nine buttons on the left side of the screen that you have a fast access to the pages that you can create a bookmark. The back is only determined that the site of the Sony PRS 505 rpm is a bit low, compared to Kindle. Readability is another plus point of the model from Sony. The screen is larger than the Kindle, which is a big plus. In addition, Sony has improved on-screen legibility AA under the light, where the words are visible on the screen in bright light. The contrast of the screen is sharp, but still easy on the eyes.
