> a 32-bit OS can only address 3.2 GB of RAM Is that true though? 32bit Windows 2003 Enterprise or Datacenter editions were perfectly capable of accessing 64GB or RAM [0]. Even so, that difference from the usual 4GB and 3.xGB was any kind of memory usage for integrated GPU or virtual address space mapping for different hardware.

I think the "3.2" figure irked me more than the usual "32bit OSes can't use more than 4GB". That's not a real limit and never was. Even people with no IT knowledge would have noticed it varies quite a bit anyway. I guess I expected a little more from a tech reporter.
