When not talking about Lenovo, most laptop/mobile gadget is selling much cheaper ONLY in US. E dot G, try look at Google Nexus in US compare to the price around the world.

Now talking about Lenovo, almost All Lenovo products in Malaysia is way cheaper compare to other brands, plus most model has TWO YEARS INTERNATIONAL WARRANTY.  (Sorry to say Lenovo already confirm won't honor grey import sets like yours and was told will make official update about international warranty term within Q3 2013)

imo, i feel that you don't have the much sense in market info at all. No offence but just my very own 2cents
