I probably wouldn't use Glass in my everyday life, but I totally see it working for tourism. Getting directions is a pretty obvious use case. But learning about what you're seeing is the biggest win. See a building you like? Ask Glass what its history is. At a museum? Get more information about the art you're seeing. Learning while experiencing sounds awesome.

Yeah, Glass + Goggles seems an awesome combination.

But even awesomer would be Glass + Word Lens: http://questvisual.com/us/

(Assuming it works well, I haven't tried it)
