J.D. Power has some interesting new data in its latest annual tablet customer satisfaction survey, as TechCrunch is reporting this morning. While the iPad fared best in the survey, Amazon’s Kindle Fire placed a mere six points behind, thanks largely to its price point. Meanwhile, tablets from Samsung, Acer, Barnes & Noble and HP finished as also-rans behind the two front-runners, with each scoring below the industry average. It’s dangerous to infer too much from this survey, but it seems to me it’s a bit of an indictment of Android as a tablet OS: Amazon has fared well because it essentially co-opted the platform, while others have struggled because they haven’t really made it their own. That indicates there may be plenty of room for a solid tablet running Windows.
