According to other industry experts with visibility into
tablet usage trends we've spoken with, the Kindle Fire HD 8.9 ″ is not Amazon's most popular model — the 7 ″ HD tablet is.
According to new research from app analytics company Localytics, the U.S., and specifically Amazon, should take the most credit for that
trend: some 59 % of all Android
tablet usage came from the U.S., with over half of that attributed to Kindle Fire and Fire HD
tablets, working out to a 33 % share.
