Heh. I saw switch at LightFair - and I asked the guy whether the envelope was made of glass, and what the liquid was made of. Both questions he skirted around. Me personally, I'd rather have broken glass and a microscopic amount of mercury vapor, than broken glass and a huge "liquid" stain. Switch isn't over the hump yet.
