It will be interesting to see the knock on effect of some upcoming consumer electronics; for example Apple was rumored to be working on a cheaper MacBook that uses an iPad CPU, and Valve is working on a SteamOS based gaming machine. Both will likely live/die based on price.
edit: looks like i had the wrong understanding, thanks to the comments below for explaining
~~~~~helps that Apple's SoC has the RAM on the main die itself. They're probably immune from these price hikes, but a lot of the PC/Windows vendors would, which would only make Apple's position even stronger~~~~
It's way too early to assume these prices are permanent. It's a supply crunch meeting a demand spike. The market will find equilibrium.
Big manufacturers also order their DRAM in advance with contractually negotiated pricing. They're not paying these spot market prices for every computer they ship.
