My standard travel carryon when I'm with my wife has a laptop, an iPad, two Kindles, a big bag of chargers (helpful at security - you can pull it out and let them re-run the main bag, and they only have to physically inspect the chargers, which will turn out to be a boring pile of wires), two good-capacity batteries, two spare cell phones (neither of us can afford to have cell phone outages lasting more than a few hours), noise-cancelling headphones, and a digital camera or two. She carries her own laptop, headphones, and iPad because otherwise my shoulder will fall off. In Germany, a security officer once pulled me aside and said "so... many... electronics..." and I politely pulled them all out and showed them. Once they realized that I just travel heavy, it was nothing. It's not what I would take to China on business (that would be a cheap Android phone with a prepaid SIM that would be discarded entirely on return), but I've taken it to Kenya and Tanzania, the Caribbean, Western and Central Europe, Canada, and Mexico. If none of them batted an eye at that for a trip of two weeks or less, I don't imagine they will care much if you're actually moving.
