Yojimbo
Yojimbo is the latest offering from Barebones Software, makers of BBEdit and TextWrangler. Don't let the silly name fool you, though, this application means business. Meant to allow you to organize the 'other stuff' in your life, this app is basically a filing system for websites, PDF's, product serial numbers, and any other random bits of text you might have.
It includes a built in search function, encryption for individual 'entries,' .Mac syncing, and lots of other Tiger goodness baked in (it requires 10.4.3 to run).
It is an Universal application that is available today for $39 for a single user licence ($29 bucks for educational users) or $69 for a family pack.
Update: It seems that Yojimbo actually is a Japanese word (I thought it was just made up because in my mind I heard 'Yo, Jimbo!' whenever I read it. I wasn't being culturally insensitive, I was just clueless (something I excel at). Thanks to everyone for pointing out my mistake.
