No problems on this end, with miix 700 + CSP. My only grips are the slippery surface (screen + tip) and the very badly designed pen. I can put up with the slippery barrel and top heavy end, but the fat tip point enclosure really nags me, since i cannot see the tip. Iv shaved some of the plastic with a knife, not pretty, but better. Does the wacom smart pen with the white (gripery) tip improves on it?
