Background: I'm going on a 2 1/2 week trip to China. I will be in four major cities, with two internal flights and two bus rides. I will mostly be staying in hotels, but a few nights in a private residence. I generally prefer to travel light, but also like to have access to useful things.
Question: Should I take my laptop? It's a Thinkpad T42 (5lbs, fairly thin). Why or why not?
