X-bit Labs today checks out whether there's really a demand for 2GB memory kits:
How much RAM should be enough for comfortable work of an up-to-date platform? Most today’s systems are equipped with 512MB or 1GB of RAM. This amount of memory has been quite sufficient recently for work in most contemporary applications. However, the memory makers and retailers started pushing forward the idea that today’s systems need as much as 2GB of SDRAM. Is it really so? Some people believe it makes sense, some don’t, but it is us who will be digging out the truth. Since there appear more and more 2GB memory kits in the market, we decided to carry out our own investigation that would show us whether contemporary computer systems will really require over 1GB of system memory.
The answer appears to be yes. You can check out their report over here.
