I've been giving the development software Espresso a spin and, thus far, have really been enjoying it. The application looks extremely nice, creates a sensible workflow, seems to have a small memory footprint and has just enough bells and whistles to not be overwhelming. I think I can safely say when the trial period expires I'll be purchasing this and making the switch from my Textmate / Dreamweaver prone ways and sticking with Espresso.

Heads up via Arlo and Chris.
