It seems that Illustrator is the flavor of choice when designing typefaces. Users seem to have a strong grasp on Illustrator and prefer the design tools in the software over others. Typography is a huge part of what makes Illustrator so accessible to a designer.
As someone who has designed typefaces from hand using illustrator and then having to lug everything over to fontLab I'm confused as to why Adobe hasn't built in the features of fontLab into illustrator, or why they haven't built something better.
