RR vs Frodo.
This is only my opinion.
I am running RoadRunner
I didn't install Frodo, mainly because there seemed to many 'requirements' before getting started.
Also I like the fact that RR is continually being updated, is easily skinnable (FP maybe as well), and the source is available so other people can have an input, and god forbid Guino decides he has enough, there are many out there who will take on the mantle.
The only thing I am waiting for on RR is dual screens, when It has that it will the bees knees (hint hint)
