Check out the "Keychain" app rather than KeePassX - it's rather nice once you get used to it. Also: Quicksilver is so much more than a quick launcher - play with it for a bit and you will discover that you can do pretty much anything in 5 keystrokes with quicksilver!

Congrats on the new mac - I remember when I got my first powerbook - one of the best things I ever did.

Also: Check out TextMate. It's the one application in the world that might make you give up VIM! IT's hard to explain textmate, but check out some of the videos on the site. It's got the hardcore technical abilities of Vi (and more) and the elegance of a mac!

I was never able to get Keychain to do anything ...

... and I had a mac laptop for a couple weeks, but sold it (recovering only 65% of what I paid, damn it) because it just didn't seem nice enough to warrant all the money I'd paid for it.

I would probably like Keychain. However, I have ~250 entries in my KeePass database and I move it constantly between my Windows and Linux machines. Unless Keychain can read and write KeePass files (which I haven't checked), it's of no value to me.

I've heard good things about Textmate. My real investment with Vim is not so much the various extensions -- though they are important -- as the muscle memory. I have over 20 years of deep-seated keystrokes from the vi family: 'dd' to delete a line, 'w' to move forward a word, 'c3w' to change 3 words, and many many more that I don't consciously think about. Until I reflexively attempt them in any other editor and leave line noise spattered over my document. When I program in C# at work, I generally use Visual Studio with ViEmu, a vi emulator. Such is the power of habit.

Checkout Quicksilver. I wouldnt be able to operate my Mac without it these days. http://quicksilver.blacktree.com/
