Amazon Kindle is a software and hardware platform developed by Amazon.com subsidiary Lab126

for rendering and displaying e-books and other digital media.

Three hardware devices, known as "Kindle", "Kindle 2," and "Kindle DX" support this platform, 

as does an iPhone application called "Kindle for iPhone".

Users can download content from Amazon and some other Kindle content providers in the proprietary Kindle format (AZW),or load content in various formats from a computer.

Concurrently with the Kindle device, Amazon launched the Digital Text Platform, a system for authors to self-publish directly to the Kindle

The google phone:

If use of the product is limited to free WiFi networks, the cost would be $529 for the lifetime of the phone On the offered T-Mobile network, 

an unlimited usage plan is $2,579 for the first two years, whereas an unlimited use plan for two years on iPhone is $3,799.

Open source:

Open source describes practices in production and development that promote access to the end product's source materials—typically, their source code.

Some consider open source a philosophy, others consider it a pragmatic methodology. 

Before the term open source became widely adopted, developers and producers used a variety of phrases to describe the concept;

open source gained hold with the rise of a public, worldwide, computer-network system called the Internet, and the attendant need for massive retooling of the computing source code.

Opening the source code enabled a self-enhancing diversity of production models,communication paths,and interactive communities.

Subsequently,a new, three-word phrase "open source software" was born to describe the environment that the new copyright,licensing,domain,and consumer issues created.
