I'm still waiting for someone to give me a use case that appeals to a broad swath of "average" users. I don't think there is a "killer app" for Vision Pro, just like there hasn't been one for the Quest.
In other threads, I think you've posted this challenge about 10+ times and I think I've shared my own answer to it at least a few of those times so here we go again...
The thing I like least about even MBpro 16" is the very constrained space in that 16" screen. When I have to go from 40" ultra-wide to 16" MBpro, my productivity plunges because I spend a bunch of new time flipping windows or virtual screens and working within limited space of any given app (even when in "full screen" mode).
MBpro 16" starts at $2499. So for $1K more than that, I perceive that I can have an any-sized screen MBpro, including my preferred desktop screen size of 40" ultra-wide.
If that works as good as implied in the WWDC video, my next "laptop" is likely to be a combination of a modest Mac in lap- perhaps even a de-screened MBpro (accessible for little from people selling it because they damaged their screen)...
...plus Vpro for the screen. Then, when traveling and wanting to get some work done, I (believe I) will have my 40" ultra-wide screen
with me... in a relatively small & lightweight package... that fits in a bag much like an existing laptop fits now.
Pull the 2 pieces out and use them in lieu of laptop. Put them away just like putting away a laptop when done.
Many tech players are trying to find ways to deliver bigger screens without the weight and size. Thus, companies are experimenting with folding devices, with rollable screens, with projector screens, etc. This is in play for laptops too...
All I see there is much heavier weight to carry around.
By virtualizing the screens, I see this as a portable, high-quality crack at
THAT very desirable benefit.
I'd like a MBpro 40" ultra-wide. But I wouldn't want to carry that aluminum monster around. I also wouldn't want that in the form of one of the foldable laptops that already exist. However, Vpro MAY deliver ANY-size laptop screen(s) minus the weight of an actual gigantic-screen version. If so, $1000 more for any-size screen (part of that) "laptop" seems towards bargain to me.
I wish to see this work in person once there are Vpro demos in store. But looking at the WWDC presentation, it looks like this works just fine... and cheaper competitors have this working well too in lower resolution variations of Vpro. I hope the opportunity for anyone wanting a bigger laptop screen than 16" has a good opportunity to get one by "thinking different" along these lines.
