The JUC 400 Wormhole switch from J5Create is a simple looking device that lets you do amazing things. Using a single cable, the JUC400 lets you share a keyboard and mouse connected to one Mac or PC with another Mac or PC, in any combination. You can also drag and drop files and folders from one computer’s desktop to the other, as well as share the contents of clipboards between them. Simply drag the cursor to the edge of one display and it jumps to the other. It’s so smooth and simple you won’t believe that you haven’t always been able to do this.
If you have an iPad and a Camera Connection Kit, you can even attach one end of the Wormhole Switch to the iPad and one to a Mac or PC and use the computer’s keyboard to type text into an open iPad app.—JIM GALBRAITH
