Grad Students Represent: Note Taking / References on OS X

My new MacBook arrived last week. As I am beginning a doctoral program in the fall, I'm interested in knowing what others are using to (1) take notes on the Mac, and (2) start building a reference or bibliography for a dissertation.

For note taking, I have Googled up quite a few, including:

• ZuluPad
• Curio
• OmniOutliner (included with OS X)
• SOHO Notes

And for references/bibliography building, I have heard about Endnote.

Ultimately whatever I choose I want to be able to stick with for my entire program so I'm not worrying about compatibility issues, etc.

Thanks in advance for your thoughts!!
