The tutorials are copyrighted and therefore cannot be downloaded.
iWork in particular
iWork can be purchased as a bundle from the Apple Store but you can download Pages, Numbers, and Keynote individualy from the App Store if the Mac is running v10.6.6 or later.
Help with the software can be access from the Help menu with any of those apps.
That is not a reason.
They could be DLed before, they were just QT movies.
The content of the entire Apple Support site is copyrighted but I can print any of it to pdf or capture it as websource.
Apple User Manuals are also copyrighted but you can download them, an obviously desirable thing to do. That applies to a vast amount of material on Apple's sites, even its commercial sites such as the iTunes Store and the Mac App Store which both have free, copyrighted and downloadable content.
Copyright does not preclude access, it just affirms the ownership of the IPR. So the connection between copyrighted and being unable to be downloaded, is a furphy.
Why make something you want people to have, to make using your product easier, difficult to access? The equivalent of putting a chain on your product brochures in a store?
I'm with you Peter. There are three brand new Aperture users in this house and we all want to watch all the very well produced introductory tutorial videos. But without being able to save them we have to download them all repeatedly so everybody can watch, and rewatch, them, at their own pace. These really should be made avaibale for download. I am aware of all the "work arounds" for downloading web content but why make it so hard?
