The main problem with the Pro is that it completely fails at the thing it was primarily marketed for: AR passthrough.
The cameras are so bad that when you use video passthrough, everything is blurry. It's completely unusable. No one will ever use it for productivity tasks in its current form. Meta should have just focused on making a high end gaming version because they failed at making it usable for anything business related.
It's because Edge is built on Chromium now.
