Yes, I know, it's another list, but here goes:
What is your favorite menulet and what is it used for?
Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back. Right-click (or ⌘-click) the icon to show the menu.
by Bjango is definitely my favorite. Monitor CPU, memory, disk usage & activity, network, temp sensors, battery, and customize the date & time format. Each of these items also has a customizable drop down menu with more details.
Fantastical is awesome for quickly creating new calendar events and for seeing what's coming up. It's got some pretty smart natural language recognition, so I can just type "Architecture Review Meeting next Thursday from 4 to 6pm in Conference Room #42", and it fills out all the fields for you. Hit return and you're done!
MenuMeters is a free application that displays CPU usage, memory usage, network up/down, and disk write/read.
A tiny, dead simple app that replaces the system clock and shows a calendar when you click on it. You can also freely customize the date format.
It always has been a missing feature: Disabling the sleep mode on a Apple Laptop. Who does not want to use it as a big juke-box or go warwalking?
gfxCardStatus is a menu bar application for OS X that allows users of dual-GPU 15” and 17” MacBook Pros to view which GPU is in use at a glance, and switch between them on-demand.

Great little menulet to hide all the files and folders on your desktop. Much better than letting clients see all the cruft you've accumulated.
One of the most convenient ways to assign shortcuts to running AppleScripts or shell scripts.
Count on it to deliver your music, news, talk, sports, from 50 countries, in 100 languages, at the blink of an eye, with a click of a button.
Lock the screen immediately if you need to step away from the computer.
In addition you can lock the keychain. Fast access to Security Prefences and Keychain Access too.
You activate this menu item by checking the Show keychain status in menu bar option in the preferences for Keychain Access:
Plain and simple...notifies you when you have a new email. It also integrates Google Calendar into the notifier. All-in-all it's a handy little tool.
A powerful VPN client that replaces all other clients you may have (including the OSX VPN setting).
VPN profiles based on networks
Growl notifications

And it's associated Safari or Chrome add-ons, which allow you to open a youtube video from a page into a small standalone (resizable window) which is great for hour+ long podcasts which don't have video content worthy of their own tab/window.
An extremely lightweight mail client for your status bar. It's been abandoned, unfortunately, but it works on Lion with a few bugs and the developer has let everyone use the Pro version for free. It has tons of flexibility, and lets you preview, reply, compose, and file messages, all from a little unobtrusive icon. It supports Growl, and uses very tiny amounts of CPU and RAM.
