Sounding like the ultimate incarnation of the big - screened tablet PC, Microsoft notes the Surface Hub experience is designed around a highly
responsive screen built for ink and touch, with both versions featuring integrated, optically bonded displays «capable of detecting 100 points of multi-touch and up to three simultaneous
