I had FrontPage 98 version (v3.0) in use. And although Microsoft has now set the development of FrontPage to FrontPage has developed great in the nine years of the product life cycle to the 2003 version. From FrontPage 2003 Two new programs came into existence: The Expression Web (tm) and Office SharePoint Designer of 2007.
The Expression Web (TM) Designer is designed as FrontPage successor to develop, design and maintain 100% -standardkonformer sites based on current standards such as CSS, XML, XHTML, XSLT, and ASP.NET 2.0. In addition, dynamic websites in PHP are initially fully supported. With the Expression Web (TM) Designer to be possible the creation of so-called "barrier-free websites" to set out by the US government standards WCAG and Section 508 (29 USC 794d) for accessibility.
CONCLUSION: In a brief Expression Web (TM) Designer Beta Test I only missed tools for convenient editing more-dimensional websites levels. Since there is still considerable room for improvement and Adobe Dreamweaver remains the number one source for levels websites in 2007. But holds otherwise the Expression Web (TM) Designer what Microsoft promises worthwhile for me to upgrade from FrontPage. Only because of the improvements when creating / editing dynamic Web sites. Also were accessibility and functionality of a site for me personally always the most important. In bold design elements such as Flash buttons, Java Menus & Co. I have never set value.
Additional Information: The Office SharePoint Designer 2007 is designed to contrast SharePoint sites and provides a variety of tools for designing / managing on servers running SharePoint technology.
