What is devicePixelRatio?
Why does that matter?
As a web developer working on a mobile product (disclaimer: I work for Yelp on the mobile site team), I care a lot about how websites are displayed on mobile devices. Very often we fallback to JS to serve the best experience for each device, and there are a couple of areas where JS is required if you want to take advantage of the new display capabilities.
Responsive images Example: http://menacingcloud.com/?c=highPixelDensityDisplays
Canvas based interaction http://www.html5rocks.com/en/tutorials/canvas/hidpi/
Many other reasons including image loading, browser height sniffing, etc.
Nexus7: what did you do buddy?
Nexus7 reports a devicePixelRatio value of 1.3250000476837158. You read right.
