its due to the processor IMO, its lack of optimization the CPU and proper gfx and performance drivers will gimp any performance no matter how much the clock speed is, and the VGA screen isnt any help either. there are youtube vids on the pro vs (the tornado i think....) where it has a 200MHZ (or 400MHZ i cant remember) but did not have these qualcomm processors we have now and it smoked the Pro in smoothness and fluidity in a game where they loaded it on both side by side

when it comes to the mogul/6700 vs pro, then the screen that hogs up the resources is the main dealbreaker even with touchflo off
