As noted by MacStories, Apple has discontinued its free trials of Aperture and iWork, directing users to the Mac App Store where the apps are available for purchase.
The discontinuation of the Aperture trial is not particularly recent, as discussion forum reports indicate that it has been missing for at least a month, but the removal has gone mostly unnoticed. It is not entirely clear when the iWork trial was taken down from Apple's U.S. site, but it appears to still be available from some international sites such as the UK site. Other international sites also suggest that the iWork trial is still available, but attempts to download the app simply lead to the Mac App Store.
Aperture is priced at $79.99 in the Mac App Store, a significant cut from the $199 price of the boxed software it replaced. In a similar fashion, the three iWork applications (Pages, Numbers, and Keynote) are available through the Mac App Store at $19.99 each, less than the $79 price for the boxed version containing all three applications.
