Spend Less Money
Ubuntu is 100% free and mostly open Linux-based OS. It means you can use it free of charge. For example, when you buy a new PC, you don't have to pay for Windows.
Support for Many Formats
This means that when you need to open Microsoft Office PowerPoint presentation, you get it open using OpenOffice.org office suite. Unfortunately, only the most common formats are supported in default installation. Many other formats can be opened by other free tools. Those tools can be found from Ubuntu's official repositories or other resources or by compiling them manually from source. If you can't open the format you want, you can ask, why it's not supported and suggest it for the developers and if it's popular it can become supported. For example in Windows, you have to pay for every software you need to open a file.
Support for a Wide Range of Different Kind of Hardware
Linux has good support for different kind of PC hardware. About every computer hardware and all its devices work at least 95% with Ubuntu. Or I think so. Linux supports the modern services like Internet, graphic user interface (GUI), sounds (PC speaker is still in use but there's also sound effects), 3D graphics in desktop and games , VOIP (Voice Over Internet Protocol) and printing. Webcam is partially supported and better support might be under development.
Better and Easier Choice for High-Quality Internet Security
Ubuntu supports many Internet services and protocols like for surfing, e-mail, file transfer, VOIP, IM... etc. Security is not the biggest problem because there's no trojans, keyloggers or other kind of malware for Ubuntu or any other Linux yet. Anyway, Ubuntu can work as a server, so the security level of webhost is provided for everyone and for 100% free.
And much more...
