"Using Web fonts in your design requires thorough testing on as many different browsers and platforms as possible, with a close look at various options for rendering text. If the screen display is of poor quality and lacks subpixel rendering, then opt for graceful degradation by serving system fonts to older browsers and OS. Conditional comments are the easiest way to exclude older browsers and operating systems from style sheets with Web fonts. Of course, JavaScript is a more elegant way to detect whether a client’s subpixel rendering is turned on."
