Motion seems to be in the eye of the beholder. Vincent rates it as sub-par even for casual users and same goes for video processing. Phil scores both as decent, but he does acknowledge some motion issues using Ultra Smooth engine. Interestingly Vincent did not experience the backlight switching off issue. Other than that most of their findings are pretty much in line.Vincent Teoh pretty much agreeing with the review. Great hardware, let down by poor software implementation.
