I've long felt Visio is a neglected product. It has much more potential but it doesn't seem like Microsoft is putting all that much energy into it, considering how many people actually use it and pay for it. On the other hand I don't even like the default Word styles. The spacing between headlines and paragraphs and coloring irks me. I guess LaTeX is still the way to go for really beautiful documents. The true gem is of course Excel.
@itsnotabug It's kind of interesting if Visio doesn't do graph layout or doesn't do it well, since Microsoft Research made a commercial graph layout library.
