My day to day job involves web development for the most part. A lot of it is bogging down with CSS and HTML alongside all sorts of other wonderful things (databases, objective-C and beyond). I develop on my recent purchase, a Retina MacBook Pro. This bodes well for anyone looking at anything I do on a retina display. In fact, I’ve been trying to use CSS as much as possible lately to avoid the sticky issue of having huge images on my work – thus saving broadband providers the pain.
I’m also relying heavily on native text rendering, because big, blocky lumps of text look beautiful on retina. With all of that in mind, smashing magazine have written a very in-depth piece about designing for retina on the web. It focuses quite specifically on the Mac but other high-DPI devices are coming, and it all rolls back to iPads (for the most part, anyway).
