From there you'll have to find your own way through the warren of computer stores. Hung Hom seems to be a very Chinese part of town, but most signs are in English as well as Cantonese. Otherwise I've had no problems travelling with a laptop. No country so far has given me any customs hassles. Even being sand-blasted by the wind in Beijing didn't seem to worry it, though it will carry the marks on the exterior forever.
Biggest problem is the battery which always runs out partway through a long plane flight.
