What do you think? Would it be of value to others?

I agree it's not needed in any way, but I think the comparison is a bit funny as the procedure in the two pilot environment is to do call out on the checklist items. Whether you read them or a device reads them to you, should be the same process, it's just a matter of personal preference. 
Speaking of silly gimmicks I think some of the recent changes, like the breadcrumbs, highlight of FIS border in zoom out and weather overlay playback is more silly, and I would prefer SD to focus on some real new capabilities.
