I have never really used the HTML features of BBEdit, which these days comprise a huge number of it's features. However, even without those features, it's a fantastic text editor. I've been doing some PERL lately and BBEdit supports syntax highlighting and checking for PERL, which is quite handy, too.

I wish they made it for Windows, too, so I wouldn't have to use TextPad when I'm stuck on a PC. Although TextPad is a pretty nice editor, it's not as powerful as BBEdit, except perhaps in custom syntax highlighting, which is easily user creatable/editable.
