ConvertIt - A great little app that can be used to convert images to multiple image formats really quickly. Just drag and drop on the icon. I’m running it as a menu bar app only but it can be configured to run in the Dock as well.Delibar - App to manage all my Pinboard bookmarks. Also an iPhone appDropbox - Just to make sure everything is in syncTextExpander - While I don’t use it to its fullest extent, it is great for typing long repetitive strings in the TerminalLocation - Just the Mac OS X Lion icon letting me know what apps are currently using my Mac’s location data.Sidekick (Previously NetworkLocation) - I use this to automate my Mac depending on where it is. For example when I get into work it will drop my volume, mount the work server drive and open up Remote Desktop Connection. I used to use AirPortLocation but since the dev isn’t supporting Lion I’ve had to switch. I only hope the devs of Sidekick add more features in the future.CloudApp - Used on almost a hourly basis to upload pictures, links, etc. for easy sharing.unDock - Great for cleanly ejecting all manner of drives be they network, Time Machine or USB/FW ones. Allows you to run scripts as well.Seamless - Transitions songs from iPhone to Mac and back again.Hazel - There isn’t enough room here to say all the good things that I want to about Hazel. If you don’t have it, get it. Think Folder Actions on steroids that have been given Green Lantern’s ring, is Superman’s secret brother, & has been soaked in cosmic rays.Time Machine - Just to monitor how everything is running.Wi-Fi - Because I’m constantly having to change networks.iStat Menus 3 - This app is great. It lets me monitor what my Mac is doing at a glance and if I need more information I simply click on one of the stats to bring up a full menu. I’ve got it monitoring my Disk Activity, Network, Disk Usage, Memory, CPU, Battery, & Date and Time. (From James Smith)

CloudApp & Droplr: Sharing documents and other files. CloudApp has a great link shortening feature (I use the keyboard wherever possible) but is limited to 25MB files. Droplr also has the much better iPhone app.Dropbox: Using it with 1Password, PKGBackup, and other things that should be stored and accessed wherever possible. Also great photo gallery implementation for simple photo sharingAdium: The one and only IMGrowlTunes: For displaying the current trackControlPlane: Automatically switch location by rules (‘WG’ is the German abbreveation for ‘flat share’ though)TextExpander: Save your time - use TextExpander!Blast: Keeps track of my recently changed/opened/created files. Very good when I’m downloading tons of documents for universityEvernote: Note taking accessible over Mac, iPhone and internetCaffeine: Prevents my Mac from falling asleepSlimBatteryMonitor: Does what the name suggestsThen the usual: Wi-Fi, Bluetooth (with MagicMouse connected), Time Machine (damn! how I hate that exclamation mark appearing on Lion when not backing up for 30min), Clock and Spotlight. I got some other apps running like Alfred, Default Folder X, BetterTouchTool and Divvy. I would have put them into the menu bar but the problem is my Mac being a MB13,3inch model. Therefore space on the menubar is rare. (From gramuel)

Tweetie - Clicking this icon will bring up Tweetie and show me my latest tweets, DMs, notifications, and more from Twitter. I don’t really like the new Twitter for Mac compared to the old one, so that is why I still use the older version.Adium - I love Adium and use it everyday. It is the best IM client on OS X by far. I have changed the menu bar icon to a 1up icon depicting a mushroom from the Super Mario games.gfxCardStatus - My Macbook Pro 15” has both Intel HD and AMD Radeon 6750m GPUs in it, and OS X only gives the user to have automatic switching between both GPUs or using the discrete Radeon only. gfxCardStatus lets me use the integrated Intel GPU only so I can save on battery life when I am unplugged.SMARTReporter - I always worry about my SSD and external hard drives’ health/S.M.A.R.T. status, so I keep this utility on at all times. I even have it so it sends me an email if it is starting to fail!MenuMeters - From left to right, I have two aqua lights that show Disk Activity, then since I have a quad core Macbook Pro, it shows me the usage from all four cores. Memory usage is next, showing me the used and free totals, and lastly, we end with network, which upon clicking on it, shows me detailed information about my current network, which is through gigabit ethernet.Airport - Currently off, as I use gigabit ethernet most of the time.Bluetooth - Currently off, but I do have it on whenever I need to transfer a file or I am paired with another device.Time Machine - I have recently reinstalled and haven’t plugged in my external Firewire drive as of yet. Otherwise, this icon is really handy to see how much OS X has backed up and its progress.Sound - Usually I have an optical cable running from my laptop to my set of Logitech Z-5500 speakers and the icon would be greyed out, but I am currently away from my desk, so I am using the built-in speakers and the icon is usable.Battery - I have my laptop battery on the left side and my APC UPS battery on the right side. I love to show both, so that way I know which one is being charged at the moment.Time and Date - I have it set to 12H time and day only, because I am so used to clicking the icon and finding out the exact day.Spotlight - I use it constantly.

I like to keep my menubar simple. There’s MainMenu Pro, where it’s easy for me to fix things in one click, there’s CoverSutra because it’s the only iTunes remote I’ve ever gotten used to since the beginning plus it’s easy to find music without having to open iTunes. Next is Cloud.app, simple drag & drop, who doesn’t love that? Then Wi-Fi, Time Machine, Time, Battery Life and Spotlight. I hate seeing my menubar cluttered with things. (From yummeh)
