Just to clear things up a bit: Tiger never was advertised to be 64bit 'clean' throughout the system. Developer documentation always said the same thing. The problem I see - and that's why I brought it up at all - is that consumers out there usually think quite 'simply', naturally. They buy G5 computers because they're '64bit'. And they'll upgrade to Tiger, because - as is simplified for them - it 'brings 64bit support'. If you look at www.apple.com/macosx/tiger/64bit.html, it certainly doesn't look like Apple tells consumers quite directly, that Tiger is not in fact 'a 64bit operating system'. However: For the consumer it won't make a difference either way. If you're interested in the details, look at the linked pages in this and the last article.

This sounds quite different from what Apple promised at WWDC, when they boldly claimed Tiger to be a 64bit operating system. The article now says that "the use of a 64-bit address space is limited to non-GUI application". The kernel, we read, is compiled in 32bit mode for all machines, whether they're using a G5 or an older processor.
