Overall impression after reading that article is much better than impression I've got after reading the description of the final product. Dunno why, but I feel sorry for 21 Inc. engineers who aimed such great goals but seem to fail to achieve most of them. For me it looks like there was set a hard deadline and the engineers were forced to release a half-baked product, I believe 3-6 months more and they would come with a much better solution...

Well, I think I'll step back into the shadows and let others to express their disappointment.
