As reported by others, u may not get the the ultimate wifi speed. But if you must have the ultimate speed, can always use a good usb wifi adapter with it.  I'm not sure how many thin & light laptops out there can deliver the max wifi speed, max HDD read/write speed, max memory speed, max graphic card speed, etc. I'm sure if u do find one, its gonna be max $$$$ as well.

I might be wrong, but as of today there aren't any sub RM2K, i5 Haswell laptop with dedicated GPU & weight 1.5kg in the market. If there is do let us know.
