But yeah, if Apple can become a medical device company, it would unlock a huge revenue stream for them. Looks like these people are optimistic, I'll take them at their word for that.
I personally don't know if Apple is willing to put the investment into the devices to make them viable as medical devices. There is a reason medical devices have huge costs, and that's largely because of the human effort involved to go multiple rounds with the FDA and other regulatory bodies to get a device approved for use in medical facilities outside of trials and studies.
This is why you’ll often see a range of display devices in operating theatres. You’ll even see iPads or other tablets that aren’t necessarily certified for use.
