Got the new ATV at work, so I decided to plug the Siri remote into my Mac to top off the charge to full (I imagine it comes out of the box with a 90+ percent charge to begin with) before messing with the ATV at home tonight. So. . ..How the F do you tell when its fully charged? There's no light on it (of course not, this is Apple) and no indication on the Mac that its even plugged in. Please don't tell me you have to look at the Apple TV screen to see the remote's charge percent.
