SHAPE Services has released iDisplay, a new universal application that allows Mac users to extend their desktop onto their iPad or iPhone. Users install a free companion application on their Mac and then run iDisplay on their iPad, iPhone or iPod touch to connect to the Mac over Wi-Fi and act as a second display. Users can then simply drag windows and other objects from the normal Mac desktop off the screen edge and onto the iPad display in the same manner as using a secondary monitor. iDisplay also allows users to control the mouse using the touch screen to select text and other objects that are displayed on the iPad or iPhone screen. iDisplay is available from the App Store for $5; the Mac application is a free download from the developer’s web site. A Windows version of the host application is presently under development.
