There's a bunch of people in this thread making the case that developers shouldn't bother supporting retina devices because they represent such a small section of the market. Ordinarily I'd agree with that sentiment. I don't spend a whole lot of time making sure my work renders well in Internet Explorer 6, because IE6 represents less than a half of one percent of the traffic I receive. But here's the thing - IE6 market share is shrinking, and retina display market share is growing. It seems inevitable that given enough time all Apple devices (and potentially many devices from other manufacturers) will come with retina displays. Which is why it makes sense to get out ahead of this trend before retina displays become popular.
