I would be inclined to agree. If you want to build a site without using a reasonably hefty piece of software a la DW, then use Notepad or textpad. Not only will you learn more an awful lot quicker, you dont have to fork out loadsa money to get your hands on it.
I've used DW for many years now, and to be honest I now use it pretty much as a text editor anyway. I tend to use the 'split' view, but do all the building in code- I quite like seeing what I'm building as I go along. Having said that, the .css editing panel can be handy when you're pushed for time.
