"SLED runs a Linux kernel, an open source software
stack, and is marketed and commercially supported as a Linux
distribution by Novell. So like it or not, how well it performs
will affect the reputation of both Novell and the whole "Linux"
user experience, the same way Red Hat products can influence the
reputation of Linux and Red Hat.
"If anything Novell has done more to improve the user experience
on SLED than other organizations (commercial or community) have
done for their own Linux distributions."
