Probably a bad idea to tell publicly here on Twitter, but yes. You'll be able to hands-on with one. (And for all the others asking: I will not accept demo requests. At least not more than three. And you need to give me a good reason, why you should get the show. )
I will be hosting an unconference session on "Making sure that a new Chrome version does not break your website" (see github.com/JSKongress/JS-Kon…) at @JSKongress . Any preliminary questions?
