On Dell's web site, there is an Ubuntu extolling its virtues.
Overall this is very good publicity for Linux, Ubuntu and Open Source, even though I disagree with some wording (e.g. on why Linux is secure).
Here are the highlights
10) Ubuntu is simple and elegant
9) Ubuntu is designed for the Internet
8) Ubuntu is "social from the start"
7) Ubuntu plays videos, songs, and movies easily
6) Ubuntu is secure
5) Ubuntu boots up fast
4) With Ubuntu, you have access to 1,000’s of free software programs
3) Ubuntu with OpenOffice is compatible with Microsoft® Office and Adobe® Acrobat®
2) Ubuntu is based on Linux®
1) Ubuntu comes pre-loaded with select Dell desktop, notebook, and netbook computers
