Most programs don't use 16GB of memory. In fact, most programs don't use 0.5GB of memory, which makes the whole mention of memory here a red herring. I was mostly thinking about a system with Core Duo beating a system with G5, regardless of the amount of memory in each.
Apparently you don't use Photoshop or Illustrator, which do grab huge chunks of memory.
I do agree that "most programs don't use 0.5GB of memory". That misses the point. Are most users helped by >1GB memory? Let's look at some applications:
Adobe applications (Photoshop, Illustrator, etc.)
CAD
Video editing
New photo-realistic video games
etc.
Doesn't matter if the user doesn't need the memory for twenty programs, only that he needs it for one of his programs.
Yes, I agree there are a lot of key pushers out there running no more than Word, Excel, email & browser. Heck, if you look around the world you will see all sorts of old (ancient?) systems running creaking applications sufficiently. Does not represent the buyers of new computers, though.
