% / EM	good, except can be multiplied (.8em inside .8em is now .64 of
		your original EM) and some consider 1em too large on
		some browsers

EX	no one uses EX

PX	good, except it can't be resized on IE/Windows which
		makes it inaccessible

PT	ONLY FOR PRINT CSS

"absolute" font keywords 	best, in that they do not get too small,
		they do not compound, and they can be resized

see
http://diveintoaccessibility.org/day_26_using_relative_font_sizes.html
on how you can use font keywords while still dealing with older browsers
that may need PX
