A recent article by Tony Smith from The Register titled "
Mac OS X 10.3 Panther will not be a 64-bit OS" caused a good deal of confusion with many people, including me. It is also caused a
heated argument here on OSNews. The basic point of the article is that Mac OS 10.2.7 and 10.3 are not "true" 64-bit OSes, but the article does not clearly explain what a "true" 64-bit OS is. This had led to a lot of claims that the article is false or misinformed, rather than just unclear, which is certainly is.
Look at the WWDC keynote on http://www.apple.com/quicktime
Watch the Wolfram Research guy talk about Mathematica on the G5.
The interesting part is from 1:43:20 to 1:43:40
He talks of 6GB of accessible memory if I understand that correctly and I'm quite sure that I do. He specifically mentions that the Dual Xeon does NOT support that.
Why would he say that if Panther did only support 2.25GB or 4GB of RAM?
