Coda: Fantastic Web Dev App
Panic has done it again! They've released a program called Coda, which doesn't do anything you can't get anywhere else, but it does all sorts of things together in such a way that it makes me want to cry at the exactly-what-I-need-ness of the package.
I do most of my web dev stuff in simple text editors and FTP clients... nothing very special. The biggest problem I have is usually managing the programs in such a way that a quick fix is quickly fixable, and a major project is still safe from accidental bugs. This program keeps the FTP to one side, the editing to another, and includes a library of useful things like PHP functions, so I don't have to be a moron and keep checking PHP.net all the time.
Seriously: if you have a Mac and do web development, give Coda a try. It's the first time I've seen a program accurately reproduce the feeling of "damn, that's so smart" that Apple does so well, but for web work.
Now I have to reconsider giving up my day job...
