Usefull Mac utilities

Some usefull Mac utilities (thanks to Tom)

For remote desktop, there is a commercial product called Timbuktu that might be better. I haven't used it but it is popular among mac users.

For utilities, etc, the ones I use most regularly are:

Fink - loads of open source programs, with the debian apt-get installer means its very easy to add most command line (and other) utilities you've used on linux and other unixes.
InquisitorX - I actually paid for this, it's only 5 dollars. Gives you a decent google suggest for the search box on Safari.
Menumeters - gives CPU/net/etc graphs for the menu bar. Also gives quick access to Activity Monitor.
AdiumX - multi-network chat client. Best one I found and free too.
BluePhoneElite - neat on screen alerts when you get a phone call or SMS (including who is calling). Also allows sending SMS from desktop.
CaminoBrowser - OSX-ised version of firefox. Quicker than firefox and looks neater but doesn't support plugins.
Cyberduck - simple, neat, free FTP client
Flip4Mac - free windows media codecs for OSX. Much better than windows media player - actually works well embedded in browser, etc.
Kismac - Wireless network scanner. Best one I think - better than iStumbler or MacStumbler
Gvim - Mac port is good
VLC - Mac port also very good.
Carbon Copy Cloner - handy for backing up whole disk to another drive.
www.serverlogistics.com - do decent packaged versions of Tomcat, MySQL to install. Adds System Preferences widgets for starting/stopping.
Native versions of IntelliJ and Sybase are decent.
Best Torrent client is Azureus of course ;-)

Hopefully that's enough to get you started !
