I remember trying Ubuntu Unity, back when I was wondering if I could be a good idea to switch Linux. But I had no patience at the time for the buttons on the opposite side of the window. I can't stop thinking that if it wasn't for that, things could have been quite different.
I'm not sure with that information if internally they are analog or not. But at least it sounds like smart limit switches, which it does make sense to be more efficient than having a computer monitoring a signal and comparing it to the desired value.
I'll have to think about it, meanwhile I'll keep calling twitter, twitter.
