@2fd7551e Windows screen readers will communicate the field as normal, but with an additional read-only state.  Other responses seem to indicate that VoiceOver doesn't do so well at that.  As far as I know, a read-only `<input>` is removed from the tab order, and it can be helpful to add it back in if the information is important and the field is part of a form.  Otherwise, it will almost certainly be missed. 

 @8ef8e73f much obliged. Cheers.
