Waterproof is the loophole! I had a suspicion Apple backing the bill was too good to be true. I wonder if they'll make all their products waterproof to utilize this loophole, or if they actually will improve for laptops and desktops.
This very loosely defines industrial/special equipment - I can imagine it would be very easy to a lawyer to make the statement that a waterproof iPhone can fit that category. Something like a Panasonic Toughbook would very easily, and it isn't too far off from an iPhone as far as capabilities and ingress protection are concerned
There are some other ongoing discussions online that are more informed on this issue than I am though.
