There are lots of Top 5 (or enter your number of choice) type lists on the internet for just about any subject. I decided to make a list of applications that don’t come with your Mac but should be added as soon as possible. Here they are in no specific order:

VLC Player – Plays every video format under the sun and then some.
Handbrake – Rips DVD’s to many iPod/iPhone/other sizes and formats
Transmission – Best Bittorrent client for the Mac
ScreenFlow - Excellent screen casting for the Mac
iWork – The Office that Windows Users wish they had :-)
Buy iWork ’09 on Amazon

Would you like to add some to our list? Give us your gems in the comments!
