im not certain, but i think mutt uses it to determine which mailboxes
listed in the "mailboxes" directive in .muttrc contain new mail.
debian also has a package called `popularity contest' which runs from
cron, looks at installed packages binary files and checks the atime to
see how often they are actually used, then reports back to the
popularity contest server with the results.

see above, atime is used by some apps, and is sometimes useful in
certain cases. it all depends on your particular usage.
