After watching the Tools of the Trade episode I noticed most of the software cost money. This might be OK for people who make a living at this stuff but what about people who can’t afford dropping $$$ on tools.
Some tools for the mac I have fond:
Smultron — awesome text editor with a live preview window.
TextWrangler — stripped down free version of BBEdit.
Cyberduck — single view style FTP client (like Fetch)
Fugu — dual view style FTP client (like Transmit)
Does anyone know good free software for Windows?
