See you on the podcast and then – next Friday for more good reads.

Apple Vision Pro is now available for purchase and customers already got the devices into their hands. This brings more and more reviews, feedbacks and other materials. Here is quick recap of everything we know so far.

Apple announces that more than 600 apps were created for Vision Pro specifically.

Researchers evaluate how our brains are adjusting to constant use of Vision Pro.

Launch day is being reported too.

You can now reserve an Apple Vision Pro demo in the Apple Store app.

Walkthrough and tutorial videos are shared by Apple on their support channel at YouTube. Also, company defends EyeSight feature as key component.

Apple also sells Developer Strap to provide wired debug capabilities for performance-intensive apps.

It is also reported that Bluetooth mice are not compatible with Vision Pro, only trackpad is an option. Intel Macs could stream their screen at 3K resolution.

There is even first teardown video by iFixit. And first exploit.

If you want to test WebXR on Apple Vision Pro, you'll need to enable some of the Safari feature flags.
