+== 製品の背景情報 ==
+
+Released in March of 2012 with no fanfare or even any formal acknowledgement from Apple, the iPad 2 Wi-Fi EMC 2560 is a hardware refresh of the original iPad 2 Wi-Fi (EMC 2415). Nicknamed the "iPad 2 1/2," this model is identical in outward appearance and functionality, but has some updated hardware on the inside. The primary change is an updated, smaller Apple A5, manufactured with a 32 nm process, as opposed to the older version's 45 nm A5. This smaller processor is believed to be more power efficient, potentially increasing the battery life.
+
+This new version carries the same model number as the original iPad 2 Wi-Fi (A1395), but can be identified by a new EMC number on the back (2560) and a Model Identifier of "IPad2,4."
