Obviously you've never used assembler.  You guys are talking past each 
other, and unfortunately you don't have a clue about what Graywolf is 
talking about.  (I think he's being a bit pedantic but...).

You simply don't know of which you speak. The 5% is the API interface 
and a few other bits necessary for platform differences (CHanges in 
the VM code to handle x86's incredibly wonky memory architecture, 
etc). The 95% is what does the actual work, all the backend code for 
EVERYTHING PS does, the plugin architecture and even as much of the UI 
code as they can make common (there will always be some). PS maxes at 
2GB memory allocation on both Windows and Mac, this is due to being a 
32bit program and being designed for the common 2GB/2Gb split that 
Windows and Mac prefer (Linux often uses a 1GB/3GB split, but that's a 
kernel compile option and varies between system).

Yep, in Unix (Mac x) and XP that means the API. Modern 
multiuser/multitasking OS do not properly allow direct access to the 
hardware. Nothing I said was incorrect to anyone who understands this 
stuff. What we are talking about is how the hardware reacts to the 
software. For example PS uses 2 gigabytes max ram in Windows (even if 
your system is maxed out with 16 or 32 gigabytes, and whatever the 
kernel will allow it in Unix (that can be changed simply in Unix, but 
not I think in windows).

And specifically, I do not know exactly how much is common code 
between the two platforms. I do not even know what PS is coded in. 
The programming language can make more difference than the hardware 
does. I figured we were using educated guesses.

I get the feeling I am talking with school kids here (lots of facts, 
not much understanding).
