I do not count factual corrections as hostile, but there were a few responses 
that came close to being rude about being off-topic, while the discussions 
about Triumphs and 110,000 horsepower engines went un-challenged.

In particular, I was able to learn a lot from CH and this discussion. I was not 
aware that Intel had re-introduced a form of segmented addressing in order to 
get around the max RAM problem. I predict THAT is going to be no fun for users 
who need large address spaces. Wintel software will have to be re-written in 
order to break the limit, whereas PowerPC software will simply have to be 
re-compiled.

Okay, but I believe I stand vindicated. It appears that you cannot actually use 
more than 32 bits worth of contiguous addressing space by a single process. 
(Thanks, Chuck!)

Perhaps this sounds like a pedantic argument, but I want to work on some images 
that will benefit from 64 bit addressing. (I have several 4x5 panoramas that 
are already too big to stitch in Photoshop.) I do realize that the vast 
majority of computer users simply want to push a button, have it come on, and 
read their email. Such users will have no interest in contiguous vs segmented 
address space!

I apologize for any perceived slight. It was not my intention to laugh at 
anyone merely for their choice of computer. I do, however, reserve the right to 
laugh at those who insist that there is no other world outside of Wintel -- 
they deserve the laughter, just as much as a Canon or Nikon user who sneers at 
our tiny, sturdy OM gems!

(Sorry, got carried away and almost got on-topic there... :-)

A lot of Wintel users accuse Mac users of being defensive about their choice. 
It's good to see the shoe on the other foot for a change! :-)
