Amazon Kindle +

The Amazon Kindle is a series of e-book readers now in their fourth generation, which enable users to shop for, download, browse, and read e-books, newspapers, magazines, blogs, and other digital media via wireless networking. The hardware platform, developed by Amazon.com subsidiary Lab126, began as a single device and now comprises a range of devices — most using an E Ink electronic paper display capable of rendering 16 shades of gray to simulate reading on paper while minimizing power consumption.
