By the way, I did like this quote:
"The need for 64 bit processing: Closer than you think.

<b>64 bit virtual addressing for the desktop will be needed many years before 4 GByte physical memory becomes common place on your motherboard .</b> The point is that the whole idea of virtual memory with page management only works if the virtual memory space is much larger then your physical memory. I actually had to save my work and restart the image software many times during the work on the large images of this article, edited in uncompressed mode. Often I had to shoot down by hand as many tasks possible with Task Manager to free virtual memory just to get my work saved. The problem is not the 1 Gigabyte DDR on my Dell Inspiron 8200. The whole problem is the 4 Gigabyte virtual memory limitation which becomes so polluted with scattered around bits and pieces of allocated memory so that it's not possible to find a decent part of continues memory anymore. All the result of course of languages like C with explicit pointer handling and processors that do not have specific pointer registers. There is no way to defragment virtual memory like a hard disc to open up larger continuous areas. The only way to "defragment" virtual memory is to save your work on time, shut down the program and restart again.I think these mission critical 32 bit bank transaction servers only work because they start up and kill small processes all the time to avoid virtual memory pollution. Imagine that you have to start killing all kinds of tasks by hand in the hope that you can save a few hours worth of bank transactions....

But hey, inteloids, keep on saying: "no one needs more than 2 GB of address space"
