Providing Suitable Environments for Different Needs
To suit differing user requirements, the Eee PC 900 comes in both Microsoft Windows and Linux versions.

The Microsoft Windows version allows more experienced users to seamlessly utilize the Eee PC through the familiar Windows interface, and incorporates Windows Live features like Windows Live Messenger for instant messaging; and Windows Live Mail for consolidated email accounts on the user´s desktop. Complementing this is Microsoft Works, which equips the user with numerous office applications to work efficiently.

The Linux version is useful for users who desire an icon-driven and easy point-and-click interface. Well suited for children or users without any computer experience, it provides a fast boot-up time– ideal for fast Internet access while waiting for public transport, or taking notes on-the-go.

Yup.  Linux is really easier than Windows according to yet another source…

(The Asus EEE PC optionally runs Windows XP or the Xandros distribution of Linux.)
