I am also a fan of "X in pure CSS" in moderation, particularly the ones that model things that I've needed to do to implement certain simple embellishments in ways where using images makes the site harder to change/maintain/retina-fy. For example, speech bubbles, arrows, engraved text, rounded objects, some types of icons, etc.
