Helping a switcher (1: GUI apps)
IRC client: Colloquy. The holy grail ? an IRC client that I find useful and nice to use, and I think I tried absolutely every IRC client on the platform. Really customizable, including the display styles, open-source, nice architecture.
Camino. If you're a regular Firefox user on another platform and a little uneasy with Safari, then you should try Camino. It is the Mozilla Gecko engine, embedded in a native GUI, including with what you would expect from an OS X browser (keychain integration, etc).
Adium: a multi-procol Instant Messaging client. I'm not -really - using this one (I'm an iChat user), but it looks quite nice and I often read good reviews about it.
Chicken of the VNC: a simple and cool VNC client. Note that with 10.4, every mac comes with a VNC server (in System Preferences, choose Sharing and then "Apple Remote Desktop", in the "Access Privileges" sheet, you'll find settings for VNC viewers).
DiskInventory X, a graphic disk usage tool. I'm using it a lot.
Non-X11, native UI Emacs implementations:http://www.wordtech-software.com/aquamacs.html or http://mindlube.com/products/emacs/index.html
A really nice port of GraphViz to OS X
MySQL Administrator: they have a native OS X version of the administration tool. Update ! they released also the Query Browser at the WWDC.
NetNewsWire: an excellent RSS aggregator. Freeware and shareware versions available.
