I'm using Duet too.

It's a little quirky - the most annoying bugs are unpredictable disconnections and occasionally screen freezes, this seems to happen mostly when my macbook locks and reopens. But these things don't happen regularly enough that it causes a major problem for me. It's a bit annoying but I can deal with it.

One thing to note for anyone considering it - it performs really well at displaying text. Things like tailing logs, or displaying docs. However, anything involving typing and using the mouse is a bit painful compared to your main screen because the lag can be tedious and uncomfortable for fast interactions. In addition, I keep the refresh rate at 30Hz when on battery to save power, which compounds this issue.

I've seen those issues as well. I it Duet more as a second display more on my win8.1 laptop, and have very strange 'disconnects' - the iPad screen just randomly goes berserk and technicolor, and I have to quit the app and restart to get it picked up. This usually happens around the same times iTunes tells me there's an update, so guessing it's related.

Ah yeah, remember having the exact same issue! Very annoying. I fixed this one by setting iTunes to ignore my iPad when I plug it in
