DreamWeaver "breaks down" alright... mostly in the areas of good coding practices and ease of use (yes, I know it's designed to simplify the task instead of making it harder, but I've found it really does make some things harder, particularly if you try to do them the correct way). Certainly if you try to hand code in DreamWeaver, it only really gets in the way. Plus it's slow.
I'd like a product like Coda or Smultron that has it's own FTP built-in like DreamWeaver, so that you can auto-upload files when you save them. I use Transmit sometimes to do that, but it's just editing the remote file and saving, not saving a local copy at the same time. I want to be able to save to both places when I make changes.
