I'm about to download Eudora version 6.2. It is unbelievable that I am still using this email application. I first started using Eudora in 1992, when Yale first adopted a campus-wide UNIX-based email standard. Eudora put a crisp, simple graphical interface right on a desktop, with great stability and humorously-worded user preferences to boot.

Twelve years later, Eudora is still simple, powerful and stable. Its search feature is terrific, locating relevant subject lines or body text in seconds from hundreds or thousands of email messages. The current version can still read old mailboxes from years ago. I think Eudora is one of the best applications ever developed for anything.
