I did try SideSlide myself for a while, and I found it to be full of potential. Great features, intuitive interface, and a nice idea to power it all. Still, compared to RocketDock, it's a memory hog, and besides, not as good looking. If you wanted to take the time to customize it, it would be a great addition to any desktop. But I still use RocketDock + FARR because of their ease and functionality.
