Ok, here is a list of software I have installed. It is a pretty good list for only a few days with the machine. Note this is for home, not for work. Otherwise the list would be way different.
Eclipse - Android and Java tinkering
Firefox - To test, not to use.
Chrome - Best browser out there, I promise!
JungleDisk Desktop - Backups and synchronization are a must for any computer.
Skype - To see people far away in real time.
Adium - To chat to people far away or across the room, while also being able to ignore them.
CoRD - I still need to get on Windows boxes.
Quicksilver - App launchers are my hidden productivity tools.
Growl - Makes Adium have cool sounds I guess.
TextMate - The most recommended Mac editor. Not sold yet, vim is the bomb.
Open Office - Because it is free, and good enough (maybe?)
Tweetie - My new favorite twitter client. Warning, not for twitteraholics, but for casual users like myself.
MySQL - You always need a database on hand.
RVM - Nifty way to manage multiple Ruby versions.
Virtual Box - Because you still might need to run a little Windows stuff here and there.
CyberDuck - Move files all over the place.
Windows 7 on Bootcamp - Just in case :)
