> I disagree. 12 V is not that much for an adult when you put it on your tongue, but with today's ubiquitous technology in everything, a toddler that puts everything in his mouth, will lead to a lot of distress and fears. I prefer the existing 5V.

But PD not only already has 20V (or 19?) which can do everything 12V can, but I hear there's a new standard for going above 100W, which, presumably, works at an even higher voltage. Not sure how removing 12V specifically helps with the situation you describe.
