I now use Aptana Studio 3, with the zen coding plugin, and for me is the best thing I ever used. It saves up a lot of time when coding and it's free . I definitely recommend it if you want something new and a bit different.
I personally ditched Dreamweaver for a combination of; 1. Filezilla 2. Firebug 3. Notepad++ and I haven't felt like I'm missing out on anything just yet lol. Most of my development is done in a 'Live' environment, as the site/sites I'm working on are living in my hosting account, but hidden behind cryptic paths, and noindex/nofollow.
