We have argued elsewhere that Microsoft has painted a bullseye on every major Adobe product. Here is the Expression Web – EW arrow aimed at the heart of Dreamweaver/GoLive for web development. Keep in mind the following restrictions for Expression Web:
a)EW runs only on Vista and XP versus Dreamweaver on Win 98, 2000, XP and shortly Vista as well as Mac OS/X;
b)EW serves up Redmonds proprietary, non-portable JScript, DOM, CSS, HTML, XML, etc;
c)EW handles less servers and databases than Dreamweaver;
d)EW does not have the extensive library of specific Web development extensions and add-ons that Dreamweaver has.
With these cautions – consider Expression Web and rate it yourself.
