KWord and AbiWord don't use "Word" as a standalone, well, word. They're clearly not Word. You're not going to confuse them, and that's the point.
And "office" became the term for an office suite, the way "calendar" and "contacts" and "word processor" are just descriptive terms too.
But "Docs" and "Word" have a clear, obvious distinctiveness that "office" and "calendar" don't. "Word" and "Docs" don't inherently mean "word processor". Heck, OpenDocs.com is for legal forms, not word processing.
I really don't know what you're arguing. Go ahead, start a word processor named just "[Company name] Word" with the space and get sued by Microsoft and lose. You don't really think you'll win, do you? This is not a controversial or blurry area of trademark law.
