Well, I expect you're absolutely right there about *ability* to use
any addressable memory. However, I couldn't understand how the video
card would take (or be assigned by the BIOS, since a 32-bit OS
wouldn't know about the 4th GB) memory from only that which was unused
by the OS, without coordinating with the OS and finding out it didn't
recognize the 4th GB...
Oh, heck, my head is beginning to hurt now :)

Absolutely no arguments there; this was why I'd settled on 3GB as the
optimum to buy for myself, having been a little disgusted by my foray
into 64-bit OSs earlier.

Well, given the high rate of technological change, I'd posit that it
was an inverted bell curve, where, as the technology grew older and
more obsolescent, it got more and more expensive again. I have noticed
this in the case of EDO RAM, FP-mode RAM, it's happening right now for
DDR RAM (DDR-1, that is) and I expect it to happen for DDR2 as well,
once the next generation of RAM technology goes mainstream. This is in
India, perhaps the case is different elsewhere in the world.
Anyway, the best buy is when the price is at the bottom of the
inverted bell - the hardware is in plentiful supply.
