i guess it is easier to be able to develop and deploy on the same platform.
some of your Windows-only applications that you need, might possibly run on Linux in some sort of emulator and you'll be able to stick with Linux :)
i'm using Ubuntu myself, and i was able to install
Internet Explorer 6 on it using
Wine. it
might work for Dreamweaver too...
Wine is pretty stable now and
the performance is also good.
