Most useful stuff: OmniOutliner, Scrivener, OmniGraffle, OmniFocus, LaunchBar or Quicksilver, Path Finder, and VMware Fusion.
Also terrific, but less focused on pure productivity: Adium, Colloquy, Fission.
Great utilities for maintaining your system: AppCleaner, AppFresh, MainMenu, Service Scrubber, Name Mangler, OmniDiskSweeper, Winclone, Tunnelblick, Toast. Growl comes in handy, too.
You might also find Leap useful, depending on how you like to organize your data.
In terms of text editors, TextMate and BBEdit (TextWrangler is the free alternative) have their adherents. So does SubEthaEdit for collaborative work. Some people like MacVim. I personally use Emacs.app, easily built from the emacs source tree.
If you do any serious hacking, MacPorts is terrific.
LaunchBar or Quicksilver: tough call. I haven't seen any Quicksilver updates in about a year, since the original developer open-sourced it. Supposedly a rewrite is in the works. In the meanwhile, I switched to LaunchBar. It's a little more responsive and stable, although not quite as feature-rich or as good-looking.
I was going to list the usual suspects, but honestly, I don't think they are anything special. Yes, TextMate is cool, but I use MacVim. Quicksilver I use, but it's a glorified app launcher that has power features that I don't need. Spotlight (for me) would work just as well. Transmit is a cool FTP client, but it's just an FTP client.
Instead, how about:
- Awaken: alarm clocks can be beautiful.
- Coversutra: awesome and functional iTunes controller.
- Screenflow: Probably the closest (functionality-wise) screencasting client to Camtasia Studio on Windows.
- Simple Comic: an bare but perfect (for me) comic/ebook reader that just works.
Tranmission for torrents. Inquisitor for Safari's search bar (though at one point it was putting in sponsored links), CSS edit for troubleshooting CSS.
