I'll chime in on this one because I bought the thing not sure whether it was going to be an experiment I rarely used as more than a toy or actually useful, and here I find myself about three weeks in wearing it not as a toy but a genuinely useful tool while working from home (and then procrastinating for a break by going to this forum).
So my answer would be, it depends on where you draw the line on AR, but I've certainly used it for a form of AR as well as at least some of its actual intended use, spatial computing (which you could argue is more MR than AR, but that's a really fuzzy distinction anyway). The more-or-less full VR stuff, I haven't used other than to play around.
What I'm primarily using it for when not just playing around (and what I'm wearing it for right now) is the Mac virtual display feature. I don't have room for a 5-foot-wide ultrawide monitor in my little home office, but I do have room to wear an AVP, and the work I'm doing would be incredibly awkward with a 16" laptop + 15" portable screen I was using to date. In fact, it's awkward with three 1080p screens on the computer at work I'm remoting into.
One could argue that the giant floating screen I'm typing on right now isn't "really" AR since I could get the same effect with a VR headset, but the reality is I can see my hands, I look down at the keyboard frequently to find the right key to hit, and I'm drinking out of a teacup on the desk, none of which would be doable without the AR-ness of the interface. The keyboard in particular would be impossible, since there's no way I can reliably hit F6 without being able to see it even though I can touch-type.
And I did do some not-for-fun spatial computing a couple days ago when I was trying to trace wires in a set of photos I took of some electrical gear. While switching between photos and losing my place constantly I thought "Gee, maybe I should try my Vision Pro". I was then able arrange five large photos at the same time around me, which made it much easier to follow between points than with any of the monitor setups I have access to, and was also kind of nice because I could arrange the floating photos in space roughly corresponding to where they were if I was in front of the equipment.
Again, you could argue this wasn't "AR" since the only need for seeing the room was not tripping on my table and couch, but it was definitely mixed-reality spatial computing doing something a flat screen can't in quite the same way.
It did give me an idea for an app that I'd buy in a moment if it exists: A digital version of the crazy red-string-corkboard in every detective movie ever. As in, an app that I could put a bunch of virtual photos from my wall in space, and then connect a virtual string between points on them. I'm not a conspiracy theory nut or tracking a serial killer, but that would be super useful for figuring out which wire connects to which.
