I'm not sure what your university library is like, but I would be careful in them. At the UWashington, at least once a month you would here announcements over the PA that a few laptops had just gone missing, and to be on the lookout/careful.

Yeah, but that's all contextual as well. If I'm in Odegaard (non-UW people: the 24 hour library) then I will not leave it out. If I am in the CSE department labs, then I probably recognise a few people in the lab at any given time, so I feel a bit safer leaving out the laptop.
