An appointment in the calendar could be linked to a contact or an e-mail. These links are used internally as well so you can link anything to anything else. This program has good support for universal links both outgoing and incoming. This program is available from and costs $39.95 (at 9th May 2013), there is a 30 day free trial version, there used to be a cut down free version but that has been discontinued. The note taking part of the program is actually not very good, just a simple hierarchical tree with no tagging, but that is forgivable as the primary focus of this program is on E-mail. This is more useful than it might seem, the whole is greater than the sum of its parts. The program supports universal links both incoming and outgoing, so when used in conjunction with a note taking program that supports universal links (Connected Text, WhizFolders and to a lesser extent Memo Master) you can link your notes to E-mails, tasks from the to do list, contacts and events and appointments from the calendar. This is not a note taking program but it does make an excellent addition to a note taking program. There was no significant slowing of the response times when using a file with over one thousand notes.

It stores its data in a database and it can only have one database open at once. Essential PIM is not primarily a note taking program, it is an E-mail program with a calendar and note taking facilities.
