Note-taking programs, and other random software, for Macs

I've been doing some research on note-taking programs for Macs. I decided on SOHO Notes, but others might like something else (especially considering that once my 30-day trial is up, it will cost me $40). Many of these ideas came from Allison's blog.

I also use Zotero for keeping track of references, inserting footnotes, and creating bibliographies. It's free!

Also found a few other interesting software possibilities for other jobs, which I like the idea of playing around with. But realistically, I will never use them.
RapidWeaver -- for creating websites
Sente -- for keeping track of new journal articles, etc. in your field. I might use this someday
VersionTracker -- for keeping updated on, um, updates to your software
PDFShrink -- for making PDF files smaller. I have my own probably inefficient system for this
SuperDuper! -- for backing up. I really should use this
OmniOutliner -- I have several friends who swear by this
DevonThink -- I don't really know what this is; it seems to be a database, but from the way they talk about it on the website you'd think it's one of those better-than-human cyborgs or something. pretty funny.
