While the screens of the Sony Reader and the Amazon Kindle are comparable, and both are excellent, there are many other features where they differ (you can click here to read our review on Amazon Kindle).

• The Sony PRS-505 Reader is more elegant and better looking than the Kindle. It also feels a little better in the hand. The cover which attaches by two small clips is much better and more secure than that of the Kindle.
• The controls on the Sony Reader are a little easier to use, especially the page turning buttons.
• The Sony Reader ties you to the computer. You must transfer everything from the computer to the device or to a memory stick to be used in the device. Unless you purchase the optional AC adapter, you cannot even charge the Reader without a computer. Kindle provides wireless capability.
• The Kindle’s simple and fast way to download books without a computer is unequaled. You don’t even have to own a computer to use the Kindle, which is a big plus. On top of that the Kindle surfs the Web without any monthly fee.
• The Kindle has six different size options, compared with the Reader's three. Those looking for a reader with large print will be much happier with the Kindle.
• The Amazon Kindle store has a much larger selection of books than the Sony Connect Store, but the bottom line is that some books that are available at one store are not available at the other, and the two formats are incompatible.
