-FocalPoint has been tested on Windows 10 systems. Any half-decent modern-ish laptop should run it. The more fixtures you have, and the more intensively you use it, the more processing power you'll need, but for reference, I run it on a Lenovo X220 Tablet from 2012, and havn't had any problems yet!
-A touch screen computer is preferable, but it will work on a non-touch screen system
-FocalPoint has also been tested on OSX- I recommend a minimum of 10.11 (El Capitan). Again, the more you are asking of it, the more processing power you will need.
-Currently, only EOS-based systems are supported- FocalPoint has been coded in such a way so as to support other systems, indeed MA, Chamsys and Hog are all on the wish list, but I'm not entirely certain yet how (if) I can communicate bi-directionally in the necessary ways.
