"4. Frugal - Linux is a frugal operating system in that
you can install it onto very small devices (routers, bootable CD
ROMs, wristwatches) and it doesn't require the latest hardware nor
does it require a new generation of hardware on which to run. You
can run it comfortably on your current hardware--no need for an
upgrade each time a new version is released.
"5. Vendor Neutrality - You aren't locked-in to a particular
vendor, distribution, or support scheme."
