Nominally, sovereignty lay in the emperor but in fact power was wielded by the Fujiwara nobility. However, to protect their interests in the provinces, the Fujiwara and other noble families required guards, police and soldiers. The warrior class made steady political gains throughout the Heian period. As early as 939 A.D, Taira no Masakado threatened the authority of the central government, leading an uprising in the eastern province of Hitachi, and almost simultaneously, Fujiwara no Sumitomo rebelled in the west. Still, a true military takeover of the Japanese government was centuries away, when much of the strength of the government would lie within the private armies of the shogunate.
What member of the Fujiwara family rebelled in western Japan?
Fujiwara no Sumitomo

Although the PC market declined, Apple still managed to ship 2.8 million MacBooks in Q2 2012 (the majority of which are the MacBook Air) compared to 500,000 total Ultrabooks, although there were dozens of Ultrabooks from various manufacturers on the market while Apple only offered 11-inch and 13-inch models of the MacBook Air. The Air has been the best-selling ultra-portable in certain countries over Windows Ultrabooks, particularly the United States. While several Ultrabooks were able to claim individual distinctions such as being the lightest or thinnest, the Air was regarded by reviewers as the best all-around subnotebook/ultraportable in regard to "OS X experience, full keyboard, superior trackpad, Thunderbolt connector and the higher-quality, all-aluminum unibody construction". The Air was among the first to receive Intel's latest CPUs before other PC manufacturers, and OS X has gained market share on Windows in recent years. Through July 1, 2013, the MacBook Air took in 56 percent of all Ultrabook sales in the United States, although being one of the higher-priced competitors, though several Ultrabooks with better features were often more expensive than the MacBook Air. The competitive pricing of MacBooks was particularly effective when rivals charged more for seemingly equivalent Ultrabooks, as this contradicted the established "elitist aura" perception that Apple products cost more but were higher quality, which made these most expensive Ultrabooks seem exorbitant no matter how valid their higher prices were.
What did the Air receive before other PC manufacturers?
Intel's latest CPUs
