More or less yes, it is slightly easier to handle.

It is clear that markup will be widely supported in Microsoft products and will play important role in STM publishing.
But it is unclear what consequences we will get for web and webbrowsers, if it will be exported to XHTML+MathML or will appear in XHTML+OMML form (and either MathML or OMML will be supported by MSIE) then we can live with it, but if we just see bunch on WordML documents on web then it will be the end of normal "browsing experience" of any kind, as it will end up beyound the browser's scope and will be just passed to Office or plugins that handle WordML.
In this context it is vital to integrate MathML (actually both but we apparently have no control over OMML) into web environment, to avoid degeneration of web into bunch of WordML (well being XML based it is more manageable then PDF, but regardless this it is not the web format) files.
But under integration into web environment I mean integration in XML+CSS framework, today it is not the time to play with HTML tags, it will not give us any new functionality that could help us to be more competitive.
