I found this article at LinuxInsider.com:
Is Now the Time to Move to Linux?
The biggest reason for migrating to Linux is freedom, said Patrick Davila, co-host of an online Linux talk show. Linux is not owned by anyone and is the ultimate community project. “In many ways, the community reminds me of the early days of computers,” he said. “People are willing to share information and help others. All one needs to do is ask.”
Your next operating system move could be to one of the half-dozen most popular free Linux desktop versions instead of to Microsoft Windows Vista. With these versions, you would not have to perform a risky software upgrade, nor would you have to settle for a watered-down Vista option if your new computer were underpowered.
The Linux operating system (OS) — already well known in the workplace for its virus-proof ironclad security — is garnering approval from consumers as the computer system of choice in the home- and small-business office.
Instead of glitzy media advertising, distributors of the various Linux versions rely on satisfied users and word-of-mouth support on the Internet to spread the news about using Linux.
