The XO $100 laptop may be a benchmark P2P case. For a start we're just listing its basic features - do tell us if
you are an XO user wanting to learn from other XO's
Activities

The XO laptop runs on Linux, a free and open-source operating system. OLPC's commitment to software freedom gives
children the opportunity to use their laptops on their own terms. Children and teachers have the freedom to reshape, reinvent,
and reapply their software, hardware, and content. There is even a button located on the keyboard that allows children to
view the programming behind many applications. The XO laptop's revolutionary interface, Sugar, also promotes collaborative learning.
Browse
Browse is a simple Web application that
allows children to access and search the Internet and share bookmarks among their friends. (See the Browse page in the wiki for more information.)
TamTamMini
Simple enough to be used by even the youngest ages, TamTam Mini is a fun, powerful way to perform
music and play instruments. (See the TamTam page in the wiki for more information.)
Chat
The
Chat activity provides a simple environment for discussion, whether it is between two individuals or an entire classroom.
(See the Chat page in the wiki for more information.)
Memorize
Memorize
is the classic memory game of finding and matching pairs with a twist: a pair can consist of any multimedia object, such as
images, sounds and text. The memory game allows children to play existing games as well as create new ones themselves. (See
the Memorize page in the wiki for more information.)
SynthLab
Designed
for older children who are ready to venture into more sophisticated sound design, SynthLab is a mini-lab for acoustic- and
electronic-circuit construction. (See the TamTam page in the wiki for more information.)
TamTamEdit
TamTam
Edit is an intuitive environment for composing music. Children can create, modify, and organize notes on virtual “tracks”,
which allow for virtually limitless variations in musical styles. (See the TamTam page in the wiki for more information.)
TamTamJam
TamTam
Jam is a fun, powerful way to perform music, play multiple instruments, and collaborate musically with other children. (See
the TamTam page in the wiki for more information.)
Record
The
Record activity provides a simple way for children to take pictures, view slide shows, and record video and audio—all
content that can be shared via the mesh network. (See the Record page in the wiki for more information.)
The Journal
The
Journal activity is an automated diary of everything a child does with his or her laptop. The Journal can be used by children
to organize work or revisit a past project, and by teachers and parents to assess a child's progress. (See the Journal page in the wiki for more information.)
Measure
Measure
is a tool that allows children to explore and learn by connecting and observing physical phenomena and real-world events.
With it, children can measure and log data and create graphs. (See the Measure page in the wiki for more information.)
NewsReader
The
NewsReader activity provides an interface for viewing news (RSS) feeds. (See the News Reader page in the wiki for more information.)
Draw
The
Draw activity provides a canvas for a child or a group of children to express themselves creatively. Children can draw free-form
images with a paintbrush and pencil, and use the dedicated toolbar to play and experiment with shapes. Text support, image
import functionality, and an interactive placement system give children limitless ways to explore their creativity. (See the
Draw page in the wiki for more information.)
Pippy
Pippy
is a simple and fun introduction to programming in Python, the dynamic programming language underlying much of the software
on the laptop. (See the Pippy page in the wiki for more information.)
Distance
You
can measure the distance between two laptops by measuring the length of time it takes for sound to travel between them. Along
with the measure and record activities, there are many ways to use the laptop to explore the physical environment. (See the
Distance page in the wiki for more information.)
Turtle Art
Turtle
Art lets children program a Logo “turtle” to draw colorful and complex artwork. Simple programming elements easily
snap together, allowing children to bring their art to life. (See the Turtle Art page in the wiki for more information.)
Write
Write
is a basic text editing application featuring straightforward tools and a simple interface. It provides an easy way for children
to write a story, craft a poem, or complete an essay, as well as more advanced features like image insertion, table creation,
and layout operations. It also features collaborative real-time editing, so a group of children can work together to edit
text easily and seamlessly. (See the Write page in the wiki for more information.)
Etoys
Etoys
is a media-rich authoring system aimed at helping children learn by doing. They can explore their ideas by creating models,
simulations, and games complete with text, graphics, sound, and video. Children can also share desktops with other Etoys users
in real time, encouraging immersive mentoring and play. Etoys has a worldwide community of users and developers who are working
to create content, curriculum, and examples. (See the Etoys page in the wiki for more information.)
Read an eBook
The
laptop has a built-in eBook reader: the display rotates 180 degrees around and folds down on the keyboard, which enables you to hold the laptop like a book
to read. The screen folds over the keyboard and the screen rotates, enabling you to read a book while holding the handle.
Read your favorite book on the laptop while sitting outdoors in the sunlight. (See the Read page in the wiki for more information.)
Calculate
Calculate
provides a generic calculator with a simple, straightforward interface. It is designed to be intuitive and readable enough
for even the youngest children to use, while also supporting more complicated mathematics. (See the Calculate page in the wiki for more information.)
Downloads
Along
with the applications built into the XO laptop is an ever-growing array of downloadable content and built-in access to popular
Web-based applications. This includes Google applications, SimCity, GCompris (a suite of award-winning educational software
for children), and hundreds of other applications. There are currently thousands of software developers around the world developing
