If you are using a Mac running OS X (lucky bastard!) there are a few utility programs you should know about. Things so essential that they should be built into your Mac in the first place! My list begins with DragThing, an amazing utility that allows you to create tabbed docks to organize apps, URLs, and anything else you need easy access to. Next is LaunchBar which miraculously (and instantly) finds files, bookmarks, apps, e-mail addresses, whatever... as if by magic... wherever they may be hiding on your Mac. I've always loved being able to grab a snapshot of the screen with Apple-Shift-3, but Ambrosia Software's Snapz Pro X is screen capture on steroids, adding dozens of options (including movie capture!). A more recent addition to my arsenal of must-haves is Konfabulator, which allows you to run "widgets" on your desktop to do whatever you want... you really have to see it to understand it. One utility you won't be able to live without once you've experienced it is Default Folder, which eliminated the failings of save/open dialogue boxes and makes them work the way they should have all along. Other handy add-ons you'll love... X-Tunes (adds fingertip control to iTunes from any app), and iAddressX (ditto, but for your Address Book), R-Name (batch file renamer), Quick Change (file attributes editor), BookIt (browser bookmark manager), and of course NetNewswire and Kung-Log (essential blogging tools I have recommended many, many times before).
