Suse is good
I tend towards a very customized selection of packages to the point that I won't even use Debian's "KDE" meta-package and get dumped with all KDE when I know exactly what I want from it. Debian gives me stability and flexability. Suse would be on my list if I was testing workstations for the regular office staff though. It just has to much default includes for my personal usage and servers.
One thing I really liked about KDE4 was it's disabling Plasma and such when machine resources where limited. My Lenovo R61 seemed to end up with Plasma disabled most of the time; I'm not gentle about what I have open at the same time though. It does provide a graceful feature loose in that regard.
Good to hear that multi-monitor is working for you. That seems to be a place people have trouble in general.
