It took a while for Apple to replace (not replace, but start using) fonts instead of the graphics on their website. And they chose Myriad Pro by Adobe. This is probably one of the most favourite and used font by designers in any website.
But truth be told this font appears in PSDs and looks very nice. But when the website is converted to HTML and CSS Myriad Pro is usually replaced by… Arial. Clients just don’t want to pay for it.
But typography on Apple website looks stunning. I am about an inch away of buying Myriad Pro to put on this and on other Creogen website.
