I was wondering what was dragging HN down :-). That said, if it translates signs in the "real world" on the fly to your native language, that would be win for business users. The "infinite screen/screens" thing has always show promise but has always been hard to execute against. The lack of them pushing any kind of gaming experience[1] was a bit telling for me. I'm guessing they haven't fixed the vomit problem. Still think it would be awkward to be in the same physical space with people who have visors and people who don't.

[1] To be fair I didn't see the keynote, just followed the website sales pitch.
