This is essentially blog-spam. The WSJ link they provide in the source has a lot more information: http://online.wsj.com/article/SB1000142405274870477460457603...
After reading the WSJ article, I find that just because it is longer doesn't mean it provides me with any more useful information that the Engadget summary.
I think I will stick with Engadget still, but everyone is entitled to their own opinion.
