16 GB in a portable, this will soon be possible

Samsung announced to have developed the first DDR3 memory chip with a capacity of 512 MB. Engraved in 50 nm, it has a consumption much lower than two chips of 256 MB.
The manufacturers of memory cards will thus have the choice between manufacturing cards of lower power consumption, and also the possibility of manufacturing with higher densities. Thus, by using these chips, one could produce cards for desktop machines of 32 GB or 8 GB for the portables.
Of course, it will take some time yet before these capacities are offered to the general public, but one should already clearly see a price reduction of the 4 GB cards intended for the portables.
PS to the attention of Apple: new MacBook Pro 17" will accept 8 GB whereas the 15" and MacBook Unibody have a bug that slows down these machines fitted with 8 GB. It would be great if you could offer an update in order to regulate this problem.
