PCW compares Amazon Kindle 2 with Sony Reader PRS 700. Two points that go in favor of Sony Reader are:
1. Unlike the Kindle, which has no backlight, the Sony PRS-700 has a light along the perimeter of its internal bezel. As a result, you can use the Digital Reader in dark environs, such as on an airplane or in a dimly lit bedroom.
2. Kindle has single micro-USB port which is supported by fewer devices (mostly cell phones). The Sony Reader has a mini-USB port which is use across most PC peripherals.
