For the past three years OLPC (One Laptop Per Child) had been trying to develop a low-cost laptop for two-million educationally underprivileged children of the developing countries. All the hard work of the organization has finally come to a full circle. An inexpensive, extremely powerful, high potential laptop, called XO, is now a reality.
In November, every one of us would be able to buy it for $200 under the program ‘Get 1 Give 1′, where a customer would pay $400 in total. One XO laptop would be sent to him by Christmas and another would be sent to a student in a poor country on his behalf. A good way to do some charity this Christmas!

What Make XO so Different?
XO simply cannot be compared with a standard $1000 Mac or Windows laptop. It is a different type of laptop that has been specifically designed to function in arduous conditions. With its white and green shiny plastic casing, XO appears like a Fisher-Price toy. CD, DVD and hard drives are all together absent. This peculiar laptop contains a 7.5 inch screen, a keyboard, two ear-like antennas, a built-in video camera, memory card slot, microphone, graphics tablet and game controllers.
The screen can be easily rotated into a tablet configuration. The resolution of the screen is 1200 by 900 pixels. This helps XO to display bright and razor-sharp images. In bright sunlight, the user has the option to turn-off the screen backlight. The display becomes black or light gray, but everything is crystal-clear and readable.
XO will be used in those places where electricity is scarce. To overcome this problem, a new type of battery chemistry called Lithium-Ferro-phosphate has been used in the laptop. Lithium Ferro-phosphate battery runs at 1/10 th the temperature of the standard laptop battery. It can be recharged 2000 times and it can be replaced for $10 only.
On an average XO consumes only 2 watts of power. Therefore, the battery lasts longer, approximately for 6-hours, if the laptop is used heavily and 24-hours, if the laptop is used exclusively for reading. The battery of XO can be charged either with a small pull-cord charger or through a one square foot solar panel.
XO runs on Linux operating system. However, it is doesn’t have the capacity to support the standard Mac or Windows programs as Windows Office, Adobe Photoshop, etc. Furthermore, the keyboard to too small to allow touch typing.
Something Very Special About XO
XO offers two types of connectivity, one is the conventional wireless internet connection and the other is the mesh networking. All the XO laptops are connected to each other via a mesh network. So, if one laptop has an internet connection, then with the aid of mesh network, other XO-users can also get online. Whenever OLPC releases a software upgrade, one laptop can broadcast it to all other XOs of the network.
XO contains almost all utility programs as word processor, PDF textbook reader, web browser, calculator, painting application, chat program, games and music programs. With one click, the user can share his paintings, ebooks, documents, etc. with his friends. XO has been designed for students, and the mesh network allows a teacher to supervise her students and also interact with the parents.
XO has three programming environments with different degrees of sophistication. These allow the user to open the underlying code of any XO program or web page. Apart from studying the code, the user can also modify it with ease. If the modifications become quite messy, the user can revert back to the original settings.
A Few Loopholes
The storage capacity of XO is 1 gigabyte and almost 20 percent of it is occupied by system software. Moreover, the processor is also quite feeble. It takes 2-minutes for the system to boot. However, once the system becomes fully operational, the speed becomes tolerable.
Despite of the loopholes, XO is capable of fulfilling the objective of OLPC, and above all, it is a good Christmas gift to give and receive.
