Using Edge, for me, has been an exercise in frustration.
Web sites taking longer to translate and scrolling a page is worse than a slide show, sometimes taking thirty seconds or longer to react to one click of the scroll wheel or the directional keys on the keyboard.
It did improve a little after I did some drilling and found about a dozen processes running in the background, which I shut down. but it still drags.
New and improved? Well, new maybe. I'm seriously thinking of wiping the drive and putting 8.1 and IE back.
