Currently I'm running Debian unstable on my old desktop (PII), so this release doesn't actually affect me, but it's nice to know. I'm also starting to use Ubuntu on a machine I generally use for testing stuff.
But still, when Debian releases a new stable, it's rather large news. Especially with those rather-new packages. 3.0 was using things like KDE 2.2.2, Gnome 1.4, and Mozilla 1.0. Over three years since the last release!
