> Vector art is not often the holy grail as it seems. Take fonts, for instance. Even though formats like TrueType stores the data in vector format, numerous resolution-dependent "hints" have to be added to make it more readable. While true, font hinting is thankfully finally going the way of the dodo. Cell phones and other handheld devices has very crisp fonts without any aliasing and hinting thanks to their high pixel density. The magic threshold is at about 150 dpi which when passed makes hinting redundant. Desktop displays are getting there, albeit slowly. To slowly for my taste. OS X already doesn't use hinting which is why if you are used to Windows fonts, os x fonts can look blurry. But with then new retina displays os x's text rendering simply looks amazing. |

Is it really so low? That's 20 dots per 10 points; surely you'd notice if a glyph was supposed to be symmetric, but it actually had 10 pixels on one side and 9 on the other. Also, Metafont does hinting, and Knuth must have intended to print taocp at a higher resolution than that.
