Last weekend I was juggling SPSS software data sets, output, a word document and statistics notes all on the same Mac laptop screen. And then I discovered the Air Display app… This allowed me to move some of my work over to the iPad window as a 2nd viewing window:
I then selected the iPad device and clicked the “on” button. The screen then flashed blue and the iPad magically became a 2nd window (the Air Display app had to be open on the iPad first though). ; ) This app is well worth the $9.99 and did I mention it apparently can be used as a wireless mouse?
