QuickCal – Allows me to add appointments to iCal in a pop up window using natural language.
– I should remove this but my ego and fear of missing out won’t allow it. ;-)
Dropbox – This should be built in.
FastScripts – Allows me to execute a few Applescripts I have come to rely on with keyboard commands.
DisplayPad – Lets me use my iPad as a second display over WiFi (Seems like magic. Likely is.)
The rest are built in stuff. Sync, Bluetooth, Airport, Battery, Clock, Spotlight.
