Butler
http://www.petermaurer.de/
This is probably the most awesome app ever conceived. Contains most of the functionality of LaunchBar and Quicksilver + several other apps too, all with a tiny memory footprint.
ClamAV

If you are worried about viruses, here is a free scanner.
Disk Inventory X
http://www.derlien.com/
Gives you a graphical representation of which folders are using up the most space. Handy for clearing out your HD if you cant find what is taking up all your room.
Eudora Mailbox Cleaner
http://homepage.mac.com/aamann/Eudora_Mailbox_Cleaner.html
Eudora mailboxes don't import easily into other mail clients. This little application helps you maintain dates, attachments, and other goodies when migrating to Mail or Thunderbird.
HenWen
http://seiryu.home.comcast.net/henwen.html
Intrusion detection system for the paranoid. Can e-mail you if it detects someone trying to get into your computer. These kind of apps usually cost a LOT of money.
iTerm
http://iterm.sourceforge.net/
If you use the Terminal a lot for the UNIX backend of OS X, this thing is definitely worth a try. Can even have tabbed Terminals. UB.
MenuMeters
http://www.ragingmenace.com/
If you like to keep an eye on CPU use, bandwidth, mem usage, this will give you the readouts. Essential on every working person's Mac.
Quicksilver
http://quicksilver.blacktree.com/
Very nice looking and sleek app launcher every Mac owner should try out.
Remote Destop Connection
http://www.microsoft.com/mac/
Say what you will about the publisher of this software but admit that it's handy. And it works quite well to tell you the truth.
SysStat Nano
http://www.islayer.com/viewWidget.php?id=21
This is a Dashboard widget which can show almost every stat about your computer at the click of a button.
Xfolders

Nice little two-pane file management app. If you ever used DirOpus or Norton Commander then this will feel familiar.
