First, love CSP very much. It'll run on any iPad. We deal with an artist in the Philippines with a simple iPad using Procreate and CSP, and he has no problems. WACOM, FAVO, Bamboo, Intuos and Cintiq tablets are used primarily with CSP, and you shouldn't have too many problems with PC. I've seen CSP handle Samsung with ease.
