In typical form, Martin would rather ignore the historical facts, make up his own, and continue to bash Adobe on this list (going OT considering the topic). Our friends on Windows have had 64 bit for awhile now. To put this into historical perspective for Martin:

From John Nack the Photoshop Product Manager, commenting on Apple’s switch from Coco to Carbon midstream:
What derailed the 64-bit train?
Until last June, Adobe had planned to move to 64 bit on Macs with CS4. But in June, Apple announced its technology plans at its Worldwide Developer Conference and that changed the situation for Adobe, Nack said. Apple provides two technologies, Carbon and Cocoa, to help programmers take advantage of operating system services such as managing memory, fonts, or windows. Initially, Apple had planned to make both Carbon and Cocoa available in 64-bit incarnations, but Apple announced at the conference that only Cocoa would be.
Photoshop is written using Carbon, which dates from the earlier Mac OS 9 era and is better suited to cross-platform programming; Cocoa, like the newer Mac OS X, dates back to Jobs' previous company, Nextstep."When they chose not to do Carbon 64, we had to reevaluate our road map for getting there," Nack said. Adobe immediately assigned new programmers to the Cocoa switch "so we could make this transition as fast as possible, but as the saying goes, nine women can't make a baby in a month. You can only proceed at a certain pace," he said.
The amount of code that employs or interacts with Carbon features is substantial: about a million lines, and all of it must at least be reviewed, Nack said. Even today, "we don't yet know how much code needs to be rewritten or touched."The Carbon-to-Cocoa switch was simply too massive to push back CS4 for just a couple months, he added."No one--Apple, Adobe, Microsoft--has attempted to move an application the size of Photoshop from Carbon to Cocoa," Nack said.
One can only fathom where we’d be in terms of color management without Adobe, Photoshop and the ground breaking functionality introduced in Photoshop 5, back in 1998. In a matter of a week and a half, we’ll again see how Adobe has supported color management above and beyond their competitors.
