Dreamweaver isn't Universal Binary yet is it? In which case running it under Rosetta would be pretty horrible? Better to get a PowerMac G5 system in that case and not an Intel one.
To the OP - Mac is a different way of doing things. Trying to hunt down likenesses to your current setup probably isn't the way to do things. If you're happy with Windows and your current setup then stick with it, but if the Windows world of viruses, spyware and instability is getting you down then the time to switch may well have arrived.
As other posters have suggested, I think you need to get to somewhere that sells Apple Mac's so you can have a good play and come to your own conclusions.
