beginning to look a little dated
I guess appearance over functionality matters to some people. I remember someone once telling me they didn't want to purchase a corporate web app because the blue used in its UI was "dull".
Personally, I think that if your office suite looks a bit dated, who cares as long as it works and works well? Where does fashion come into it?
One reason I like Linux is that prettifying-for-the-sake-of-it doesn't happen too often. Some of Canonical's "design" missteps aside. If you want software that doesn't "look dated" and is targeted at the "general home or small business user" perhaps Linux shouldn't be your first choice.
