John Gruber says they work great. I guess we will see.

On another hand, ARM Macs can run some iOS/iPad apps, and plenty of them work great and with zero issues. Not all, ofc, but many do. I think it’s because of zero expectations of them having to fill the entirety of your screen, so you just have it running in a window on your desktop, and it is quite good.

I would assume the situation with Vision Pro would be closer to Macs running iPhone/iPad apps, as opposed to iPads running iPhone apps. Mostly because of a similar “desktop with windows” feel I get from visionOS videos I’ve seen, as opposed to the “smartphone experience” feel i get on both iPadOS and iOS. Until I get my own hands on a VisionPro unit next week, this is just pure speculation though.
