We were supposed to get a little preview of Google’s CES booth ahead of the official opening of CES today. But that wasn’t meant to be. See, it’s raining in Las Vegas and Google’s two-level outdoor CES booth clearly wasn’t meant to withstand rain. My guess is that its IP rating is probably somewhere around 50.

For now, the booth is closed, with tarps covering the roof and all of the electronics inside and out.
