An introduction to Ubuntu:
Ubuntu is “Linux for human beings”, a complete open-source operating system which aims to make Linux simple and a solid option for everyday desktop use. It includes common applications such as a web browser, e-mail client, and a complete office suite that is compatible with Microsoft Office and other document formats, such as the new ODF standard, the rapidly growing standardized format for the future of office documents.
Ubuntu is available completely free of charge, in keeping with the founding principles of the Ubuntu distribution. Ubuntu's active, growing community is one of the core aspects of Ubuntu, with users participating in such ways as providing free support for others, exchanging ideas and suggestions, and developing software, all as volunteers.
Ubuntu is much more stable and less prone to security holes, viruses, and spyware than Windows due to a different security model, is entirely themable and customizable to fit your needs and preferences, and has huge quantities of software available to go with it, all easily accessible and free. Many of these applications, including the office suite, are even available for Windows, so you can comfortably use the same thing on both systems.
You don't have to give up everything you know and jump in headfirst. Ubuntu's Live CD lets you run Ubuntu entirely off a CD without touching your existing Microsoft Windows or Mac OS X installation at all, with no risk of losing data or breaking the existing installation. You can even install Ubuntu without erasing your other operating system, in a “dual-boot” configuration which allows you to simply choose which one to use when you start the computer and share files between the two systems.
Ubuntu is also available with multiple “graphical environments”, that can each be further customized, since everybody has different tastes for the “look and feel” they're comfortable with. Disks are available today with one called “Gnome” as well as “KDE”, so you can try either of those, and if you'd like to take a look at others (like XFCE), screenshots of all versions (called Ubuntu, Kubuntu, Xubuntu, and one even specially tailored towards use with children and schools called Edubuntu) are available at http://shots.osdir.com/.
These CDs are from the 7.04 (April 2007) release and being given to you to make Ubuntu available to people who might otherwise not have been aware of its existence, or of free software in general. Open-source projects such as Ubuntu develop at a rapid pace, so exciting improvements and new features are always becoming available, so watch for future releases too, with the next one coming up this October.
So, feel free to pop the CD in and reboot into the Live environment to check it out. If it doesn't really appeal to you, or you choose one graphical environment over another, please pass unused CDs on to a friend, relative, or coworker you think might be interested or leave it somewhere, like the break room at work perhaps. If you like what you see, just click the “Install” icon on the desktop and enjoy!
The current release supports PC (Intel x86), 64-bit PC (AMD64), PowerPC (Apple iBook and Powerbook, G4 and G5), and Sun UltraSPARC architectures, so if you need a different CD, you can download them [http://www.ubuntu.com/download] or get some shipped for free [https://shipit.ubuntu.com/].
