Okay, I am finally onto Microsoft Office 2007 (Err! But isn't it 2008 already?). Silly me, that is the problem with versioning your product by year – that the year you don't have a product, people using older product feel weirdly outdated and developers make the world feel that they are not doing enough to get a new release out.
Think about it, What Windows Operating System came after Windows Server 2003? Do you remember? Ha ha.
