アプリケーション
基本システムを拡張する取り組みが３種類あります。それは調査用ツール、表現用ツール、そして協力用ツールです。 組み合わせについては、hereを参照してください。
There are three types of activities distributed with the base system: tools for exploring, expressing, and collaborating. A matrix of applications that have been (or are being) built for the laptop can be found here.
ツール(調査用)(Tools for exploring)
- a web browser built on the Firefox engine;
- a simple document viewer based upon evince (including the ability to view PDF);
- News Reader, an RSS (“really simple syndication”) reader (PenguinTV);
- multimedia playback using gstreamer (the Real Networks Helix™ platform has been ported to the laptop and is available for download but is not part of the base distribution);
- OpenDocument Viewer to read documents in OpenDocument format, a highly-compressed format that is a fully open international standard (ISO 26300);
- The Opera web browser and the Real Networks Helix™ platform have been ported to the laptop and are available for download but not part of the standard distribution.
- Measure, a tool for exploring the physical world by measuring DC and AC voltages, observing them on a oscilloscope like interface, being able to watch waveforms in frequency domain (spectrum analyzer), logging data at a specified time interval, and drawing the graph of logged data.

共有されるアプリケーション
全てのアプリケーションは、Journalによって共用データを共有できます。 そして、読む、書く、録音する等を行う殆どのアプリケーションはネットワーク(子供たち同士、先生と子供)を通じた共有が可能です。
All applications share a common data store accessible through the Journal; Most applications, including, reading, writing, recording and browsing, allow for collaboration; through the network: child-to-child and teacher-to-child.
メッシュネットワーク

- Ability to act as a mesh point when laptop's main CPU is off;
- Support for asymmetric links/paths;
- Incremental releases—mesh networking is available immediately on XO; Upgrades will continue to improve functionality and adherence with standards;
- Simultaneously acts as a mesh point and an infrastructure node.
- Standards Compliance: follow 802.11s draft when possible.
