I'm not quite clear on what's being 'tested' in these videos. The idea is give a practical visual comparison of really, really fast things to google chrome loading a web page.

Because it's so practical, you don't need a tesla coil to duplicate it yourself (and be disappointed). Go to google, search for pandora, and click on the first link. Okay, so clearly they're not talking about transfer/load/rendering times. Let's click refresh. Well that was quite a bit faster, wasn't it? But still no lightning bolt.

Cool video, but I'd be worried that users will be underwhelmed when they test it for themselves...
