Works great, when it works
I have been using Air Display with my iPad for a couple of years, and it has usually worked pretty well. I recently acquired a second Mac Pro, and wanted to use it as an extended display for my macbook (which is running Air Display Host) when I don’t need to be actively doing something with it. Most of the time, it works great. However, on an average of once every couple of days, it crashes my macbook, with a nice gray screen, and an automatic reboot. Fortunartely, I have to give credit to Apple with Mavericks, because most of the time my Macbook reboots flawlessly. However, when it happens right when I’m editing some code, I have lost a bit of work in the process. If it was a solid product, I would easily give it 5 stars. It is really nice to be able to simple swipe my screen between my extended display from my Macbook, over to one of my primary screens for the Mac Pro. However, it needs some critical bugs to be fixed. These bugs seem to surface the most when I use Mission Control, but not always.
