The Cinevate Pegasus Cabon system looks to be like a very useful slider style dolly. I have yet to embrace the slider system and still use full size track dollies myself, but sliders take up very little space and can easily add motion to any shot. The Pegasus seems to have some cool features. The Pegasus Carbon Dolly retails for $895. Here is a rip from the Cinevate website.
“The Pegasus Carbon based Linear Tracking system is a truly revolutionary camera slider system. Designed for loads under 15lbs, the parts can be re-tasked as a super compact table dolly, overhead tracking system, cable system, and the conventional linear sliding system.
The new “All Terrain” legs give you extra height to deal with uneven ground. The over-molded, non-skid, ball feet are designed to withstand rough ground while being gentle enough not to damage delicate surfaces. With this system you can sit the unit anywhere.”
