HK is consider AP set here. No international warranty.  We dunno whether it is cheaper or not coz Samsung Malaysia not yet announce the local price.  But since the local AP set prices are drop close to RM2k now, i doubt HK set can be cheaper by a lot.  At least buying local AP set will give you local AP warranty, some up to 2 years.  If got problem can go back to them.  HK?  Only if you go there often for business.

It's consider AP set and the problem is you don't even have any warranty locally. Worst than you bought AP set locally whereby they do provide warranty by the importers.
