Kanex just unveiled its SnapX today, a $69 switch that connects a single 24- or 27-inch Apple Cinema Display to a pair of Macs and allows toggling between the two.
The SnapX will connect to practically any Mac — iMac, MBA, MBP, Mini, you name it — through the display (or Thunderbolt) port. Beside standard video output, iSight camera images and audio can also be output through the connected Cinema Display. Bummer: The SnapX will also eat up a USB port on each connected Mac; and there’s no support for iPad output.
