Consider how meta originally marketed it in a business setting - would the "virtual office" application allow you to check your private messages in between? This can be built in of course, but currently it looks like an afterthought at best.
I talked to some trainers in a company about VR trainings (my previous company produced such a course). Some trainers were interested in VR because it "keeps trainees from looking at their damn phones"
To extremely varying degrees some of this is already somewhat possible, but at the end of the day the Quest is just a low to mid-range phone running a proprietary nailed-shut android OS that's barely hold together by duct-tape. So Meta can't do much with the foundation they built, just like a tablet device its just a toy you aren't supposed to do anything real with it. Some of that is also the reason why Carmack left [1].
