Works Even with Old Hardware!

I first bought and tested this app using my iPad Air to see how well it would work as a 3rd monitor on my desktop workstation. It worked absolutely brilliantly, with no noticable lag even when playing HD video! Since I didnt want to ruin my iPad Air by leaving it plugged in all the time, I went out and purchased a used 1st gen iPad from Craigslist to act as a permanent 3rd monitor. The 1st gen iPad doesnt work quite as nicely since there is some noticable lag when dragging windows around and videos arent quite as nice (though theyre not horrible either), but its stil lgood enough to keep around! Highly recommend!
