Curious as I always am I was wondering what code editors/IDEs others are using?

I used to use Dreamweaver pretty much exclusively, however I suddenly realised that I was only using half the features as I design in code alone. So I decided to look for a lighter weight alternative that wasn't clogged up with the wysiwyg that I don't use.

After a lot of shopping about I now use Aptana Studio (which is FREE!) and I have to say I am loving it! Some of the features match up to DW but it's done in a far more coder friendly way. Add to that the ability to import/update a number of language packs and libraries that tell you when updates are available and you have a pretty comprehensive product. It also has libraries available to assist in the development of Adobe Air and iPhone application development.

So whats your flavour of editor or IDE and why?
