I have certain times of the day where my Mrs watches her soaps which means I get 2 hours of uninterrupted game time, which is when I pop on my headset and off I go. I often have a drink as well which does involve me lifting up my headset and sipping before sliding my headset back on. Think of it like a baseball cap and that's basically how it works. If someone wants to try and drink with a headset on, good luck with that lol. Being a shift worker and my Mrs being a 9-5 worker also gives me some toher times to play of course, so it isn't a problem for me.
Alt and Tab works flawless and no issues at all. Motion sickness isn't something that affects me really but if you have a hangover from hell, you might want to leave it alone but then again, I leave all gaming alone when I am hanging
My gripe is people who knock things before trying. I remember your good self saying you don't need 120Hz, as your TV you game on is perfect.... You got a 120Hz (or 144Hz) and you was like "Wow!!!! this is amazing", you then said you wasn't interested in G-Sync or Freesync, you then got a freesync monitor and was like "Wow!!! this is amazing". I am just using you as an example and not personal but people should at least try it and it is nothing like 3D and shouldn't even be compared. 2 completely different things and not even close to the same level. 3D has nothing even close to what VR offers.
