It never bother me, except what you talked about, is some very particular tasks, some task like filling a glass of water can be challenging as I have no parallax, so no real depth of field. Sometimes I can't tell if your glass is right under my jug or not. Sports with ball, forget it, ping-pong and badminton was just impossible for me in high-school/college. Bumping into things happen often, and no 3D movies for me, also VR is a lot less appealing and immersive :(
