I just noticed this today, and now it's really bugging me. Internet Explorer (11 in my case, may not matter), has a delay when you touch buttons or links. Using a mouse is instantaneous, but using a touchscreen adds around a ~500ms delay. Chrome does not have this same delay.
You can try it out yourself by visiting a sight like Bootstrap which uses anchor links on the side menus. Using a mouse, you can navigate instantly in any browser. Using IE specifically with touch creates a delay on every tap.
Most people probably don't notice it since we spend much of our time waiting for pages to load.
How do I turn off this delay?
