For what I could understand, but it may just be the language barrier here, I think the 3GB problem the AC mentioned I believe that applies to the virtual address space of applications that can only have 2-3GB for data because the remainder of the address space is reserved for code mapping... in real hardware, yes, but to the virtual address space. Because when it comes to physical memory, AFAIK the NT kernel has since long been able to use PAE.
For what I could understand, it seems to be a workaround like creating some sort of memdisk or memory used by the plugins as being other processes but still not directly mapped to the Photoshop virtual address space itself (the document talks even about more than 4GB like &GB and 8GB, but with 32bit you can only directly address 4GB and of those 4GB depending on the operating system, 1-2GB are reserved for code).
Sorry, but I think you're incorrect. The OS can give the applications a virtual address space of 4GB as however it sees fit. Applications don't see the devices memory mapping zones. Since the Pentium Pro that the x86 processors have extensions allowing them to actually use more than 4GB of physical memory independent of the virtual address space. They had a 36bit addressing scheme that would allow them to address up to 64GB of memory. One thing is the linear adressing of the physical memory in a flat addressing model (visible by the OS and in which there will be gaps for mapping devices and leaving some upper memory accessible only by remapping it), another thing is having a virtual address space. If you had 64GB of memory you could have all your applications scattered anywhere on those 64GB. See http://en.wikipedia.org/wiki/Physical_Address_Extension/. The 32-bit applications always see their own 4GB virtual address space (that can be mapped as randomly as you can possibly imagine) independant of the physical resources. That first 1GB is actually reserved to maping code between the OS, DLL's, etc, allowing the application to call system services and shared libraries.
And you have to keep in mind that Photoshop isn't the average "Paint" product for the average joe home user, it's a product developed for professionals (and with "professional" prices...). It's intended for those who need it at the point that they can afford it and the requirements for the kind of work they need to do with it. So, yes, going 64 bit is good and important for Photoshop.
Well, still it's not being elitist. Because what I consider to be a waste you may very well find it useful, but at the same time the opposite may be true. Or are you telling me that the whole of the internet is useful for you? Do you even use more than 1% of its contents? I wasn't providing specific numbers, or trying to insult anyone (you do seem pretty insulted, don't know why) or being elitist. The internet is, I'm not. I didn't try to decide what should and shouldn't exist on the internet. It's all relative and your just being overzealous in the interpretation of what I said and not really getting the point. Losen up.
Well, it will run faster if you have a large pool of physical memory and do some heavy Photoshop editing, because Photoshop will be able to access more than 3GB of memory (remember that 1GB of the 4GB address space is already reserved for system code sharing) and not resort to it's own swap/disk cache system as much.
I didn't mention the 70's games. You really need to read more carefully. And I do support egalitarianism, but the fact that I support it doesn't make it true. The fact that I support it doesn't change the fact that the net is indeed elitist.
I used to think the net was alkaline when I was a kid...
You canadians are all alike...
But soon enough I began to see it is actually corrosive.
Net neutrality? (the Acid tests come to mind...)
No net neutrality. Just net caos. About 40% of the permanent content on the net is either useless or dangerous. Of the remaining 60%, 30% are becoming casualties of war under copyright battles. And the of remaining useful 30%, about 15% is under some sort of public domain or open license. The net should be like an airport duty free, but it's more like Christiania
But it may still keep rising. If people went on redeeming their gift cards, new users for iTunes store will appear because people that have never used or thought about using it will experience a "forced" try at iTunes (either they go there or waste some "money") and may actually like it, or find it at least usable enough to go there again - the first time is always the hardest, right?
Companies that can afford such a scheme, can afford the means to prevent them from getting caught or to prevent them from getting convicted even if they get caught.
Yeah, that's very cool and then, soon after you get paid, you "accidentally" die of some cause that coincidentally doesn't harm the body parts you sold.
Similarities: There's an episode in SGA where they come across a world where the punishment for every crime was the exile to the island that hosted the stargate. The Wraith would come through the stargate and feed on the prisioners and leave the remainder of the world untouched. Until the SGA teams screwed up their very effective way of living, of course.

Tetley icons and darjeeling files...
both in windows and linux it can be up to 2GB...
no, that's not it. You can actually have 64GB of physical memory on a pentium pro. I'm not talking about swap. read the article
OMG, this must have been twitter's least bashing and less far from the truth comment I've ever read!
sorry... I had to do it =P

No, I mean the concept of what a duty free was supposed to be and publicized as, and not the concept it actually is.

The case too, the logo you'd have to stick in it has a minimum case requirement.

off-topic btw: great sig
I'd mod you up, but I have no mod points...
two days? wow, you're fast!
first we should do some testing. we should call in some experts. where's Achmed when we need him?
(probably blowing up a blue Prius or something, for a klondike bar)
just fire a bunch of nukes all around Earth at the same time with nanosecond precision and you'll get your doomsday scenario.
We have. 50 years ago. Starts with an A.
this sounds something to be added to the urban dictionary: mercury measurement with fish as units. or the reverse.
