I agree... I think many of us have been saying that for years, too: http://www.codinghorror.com/blog/2007/06/where-are-the-high-...

Despite the fact that many people primarily associate "Retina" with the iPhone (because that is where it was introduced first), I think this is the area in which it has actually had the least impact. Other phones had high DPIs before the iPhone 4, and the difference between the best Android displays and the iPhone 4 display was not overly dramatic.

OTOH, pushing laptops and tablets out of low-DPI land is a truly remarkable achievement. Other platforms are much farther behind in this area, IMO, and at least on laptops have a much longer path to catching up.
