Macromedia Freehand, in particular deleting bezier points but keeping the shape intact (ie simplifying).
Illustrator still hasn't quite caught up. For any illustration, it's useful to have as few control points as possible. This is particularly useful when making SVGs for the web; it renders faster, and an ability to hand edit the SVG is useful for animation etc. Every font design package has this feature; Illustrator, even now, has nothing that does anything close to the same degree of accuracy. Occasionally they'll roll out an improvement in 'simplify', but I find it staggering that they can't just implement what is a fairly simple feature.
