Comic Sans does serve one good purpose; it's a dyslexia-friendly typeface. It's nice that Comic Neue preserves some of the letter "hints" (ie. the "b" and "d" glyphs have slightly different bottom terminals).

Although if you're trying to optimize specifically for dyslexia, you'd be better off with something like OpenDyslexic [1].
