The trend will continue due to a combination manufacturers being able to increase output. Thanks to the use of immersion scanner technology that improves yields in their fabrication plants and the unusually low demand for memory. And i think the success of Windows 7 has a great effect here. It's basic economics: an increase in supply and a low demand leads to excess supply leads and thus lower prices. That said, economics tells us that this won't last forever, since a lower price means an increase in demand to accommodate the improved yields, and eventually a relatively higher price. Thus, the market will eventually return to equilibrium. And start of this situation is triggered by the devastation result of Windows Vista failure.
Still, the next year is good news for PC manufacturers and consumers, and not so good news for memory makers. Falling DRAM prices normally mean PC buyers will find bargains when shopping for new computers. While prices will fall for DRAM modules sold in stores, OEMs may choose to offer better overall systems instead of lowering prices. DRAMeXchange says the market will bottom out around the first quarter of 2011, and PC makers will take advantage of the cheaper RAM prices to boost the amount of memory systems ship with. Specifically, it predicts a 36 percent increase for desktops, a 31 percent increase for laptops, and a huge 105 percent increase for netbooks.
