The author seems to be stuck in 2011 when device UIs were rough, behind the curve, and the promise of a pure Android device would save the platform. The "second rate" Galaxy S3 is now massively outselling the Nexus and is the only Android device to outsell iPhones last summer.
It's just marketing. IMO, the GSIII is not a bad device, but pure nexus with Jelly Bean from google (hspda+ version, not the verzion nexus which should not be called a nexus device) is the best android (or any mobile OS) experience.
My point is numbers don't lie. The author laments the GS3 as second rate yet it's clearly the most in-demand device. The author is either deluded, had writers block (and dredged up an old premise), or hoped this might be a popular new link-bait topic.
