'iPad Mini' Name Confirmed by Smart Cover Part Descriptions
Smart Cover for full-size iPad
Japanese blog Mac Otakara claimed in late August that Apple would use the long-standing "iPad mini" informal title as the official name of the device, and it appears that this is indeed the case. Others have, however, been advocating for alternative names, such as noted Apple pundit John Gruber having expressed his preference for "iPad Air".
The new iPad Mini Smart Covers are said to be available in red, dark gray, light gray, pink, green, and blue.
