I found a neat demo of drag-and-pop technology. The concept is... when a user wants to drag an icon onto another one, why make them go the whole way? It's very intuitive, and pretty snazzy. When you begin dragging, the program looks at icons in the direction you're going and "rubber-bands" them to the one under your mouse. The original concept was to compensate for having to move the mouse several times on high-res, large computer screens, but it works great on small screens too. I'd love to see this implemented as an add-on in Win 2K and other non-MS operating systems.
I ran across this at channel9.msdn.com while looking for something else. It's Microsoft Research's blog.
