Yeah, there's something about the kerning that is just a little off. I agree that what happens on the page in the center of the screen has to be 100% perfect for any word processor.
I was thinking more about the printed page. I can deal with bad kerning on-screen if it prints out beautifully, although I won't be happy about it. But the whole point of the word processor is to print out text, so kerning is an essential requirement.
