To back up raquo here, Coda (http://www.panic.com/coda/) is my current editor of choice for most things. It's got great collaborative editing, a very nice UI, good syntax highlighting and plugin support.
Coda is expensive ($99) but the convenience of working on remote files via SFTP within the program is unmatched. If your session gets disconnected in the midst of editing a file, nothing to worry about, Coda will automatically log back in for you and update the file you were working on when you save.
You're right, but then I could also argue that any of these programs can be replaced by installing a linux port via fink and a combination of shell scripts.
My point was mainly comparing Coda to other GUI text editors for the mac. It has other useful features such as one-window editing, integrated terminal, ability to preview CSS/HTML changes side by side with code, etc.
agreed. but many will use more than $99 worth of their time to figure out how to use it. If you've already paid the price for learning VIM, its an easy choice.
