The 100 $ Laptop

Its the computing counterpart of the Nano, just like the Nana stands to be the cheapest car at 2500$ the One Laptop Per Child (OLPC) Foundation's XO laptop is a 100$ Laptop. the worlds cheapest one !! The OLPC Foundation aims to provide these laptops to millions of children throughout the developing world in order to improve their education and their quality of life.


The XO laptop was designed to be lightweight, cheap and adaptable to the conditions of the developing world. While a $100 laptop is the goal, as of September 2007, the laptop costs about $188. Originally the OLPC Foundation said that governments must buy the laptop in batches of 25,000 to distribute to their citizens, but a new program will soon allow private citizens to purchase an XO.

As of Nov. 12, 2007, the Give 1 Get 1 (G1G1) program allowed U.S. residents to pay $399 to buy two XO laptops -- one for the purchaser and one for a child in need in a foreign country. The program's initial run lasted two weeks. To start, laptops purchased through this program were given to children in Afghanistan, Haiti, Rwanda and Cambodia. More laptops should be available for sale in the future, and more developing nations will be able to apply to join the G1G1 plan.

As of September 2007, about 7,000 laptops were being tested by children around the world. Many governments have expressed interest in the laptop or verbally committed to buying it, but some haven't followed through on their promises. Still, enough computers were ordered -- observers estimated more than three million -- that full-scale production began in July 2007.

The Technology !

The XO laptop's design emphasizes cheap, durable construction that can survive a variety of climates and the rigors of the developing world. The machine can withstand dirt, scratches, impact and water while also providing long battery life. Every feature is carefully engineered to conform to these standards and to minimize the need for maintenance. To that end, the XO laptop has no moving parts -- no hard drive with spinning platters, no cooling fans, no optical drive.



Unlike most commercially available laptops, the XO's display is readable in full sunlight. Users can switch between color and black-and-white viewing modes to save energy. The screen "swivels" around, making the computer into a tablet or e-book.

The 433 Mhz AMD processor and 256 megabytes of SDRAM are unimpressive by today's standards, but the XO has ample speed to run its lightweight, no-frills software. The XO's processor is designed to be energy efficient, and several devices are available to recharge the battery, including an electrical adapter, hand crank, foot-pedal and solar-powered charger.

Rather than a traditional hard drive, the XO has a 1 gigabyte flash drive, similar to what's used in USB thumb drives, the iPod nano and digital camera memory. Google will provide online storage services, and some communities or schools will have servers with large amounts of hard drive space. The computer also has an SD memory slot to add more storage.

Like most new computers, the XO has an integrated WiFi card. But it does have something most computers don't have. The XO's green "rabbit ear" antennae boost the wireless card's range up to 1.2 miles [source: BBC News]. The computer isn't dependent on a router being nearby either. Instead, XO laptops can form a mesh network; any computers within WiFi range can connect to one another and share Internet access through a computer that's within range of a wireless connection. Think of it like a line of people, with each person touching the shoulder in front of him. The person in front may be the only one closest enough to a router to access the Internet, but that Internet access can filter throughout the mesh network.

The XO's durable, waterproof plastic shell has an integrated video camera, microphone, three USB ports and speakers. Its keyboard can be adapted for different countries and alphabets.

The Red Hat software company supplies a version of the popular open-source Linux operating system. Other software includes a Web browser (Mozilla Firefox), a word processor compatible with Microsoft Word, a PDF reader, a music program, games and a drawing program.

Whether the XO laptop changes education and community life in developing countries remains to be seen. World leaders such as Kofi Annan have praised the device. The XO has the potential to be an incredibly useful and empowering educational tool, changing how children and communities learn, interact and relate to one another. But it will take years to gauge the project's success. If nothing else, elements of the XO's award-winning design will surely find their way into commercial laptops.
