Touchscreen features in smartphones and tablets are satisfying perks in going wireless and mouse-less in mobile computing, but now Microsoft wants to make people aware of how much more satisfying the touchscreen experience might be.

The video succeeds in suggesting what the speed-up might feel like, from finger to screen. In brief, goodbye to finger lag.
