I use notepad for my home projects, but ive just started a job as a junior web developer and we are using dreamweaver at work.
Its quite complex and is hard to get used to (only been using it a few days). It utilises templates and such, is quite weird, but in time, i'll get used to it. You can set up 'testing servers' and bits and bobs.
If its just for simple use, then I wouldnt recommend it. Like someone else pointed out, use notepad, or notepad++ (ive heard is quite good). Dreamweaver is going to be expensive and will offer you the same as a free alternative.
Hope that helps.
