As reported by IW:
The “bored now” are users who have time on their hands. People on trains or waiting in airports or sitting in cafes. Mobile users in this behavior group look a lot more like casual Web surfers, but mobile phones don’t offer the robust user input of a desktop, so the applications have to be tailored.
The “urgent now” is a request to find something specific fast, like the location of a bakery or directions to the airport. Since a lot of these questions are location-aware, Google tries to build location into the mobile versions of these queries.
This definitely makes sense. In short: remember what people keep coming back for, constrain to location if they need something right away, and tailor to the medium.
