Apple's iPad mini is among the iOS devices getting a fresh update for 2015 today. Following on from the iPad Pro, "the biggest news in iPad since iPad," the mini tablet's refresh is rather less revolutionary. The new iPad mini 4, says Apple, packs "the power and performance of the iPad Air 2" into a smaller mini enclosure, which now weighs just 0.65 pounds. That's a hair less than the Wi-Fi-only iPad mini 3's weight of 0.73 pounds. The iPad mini 4 will be priced from $399, replacing the mini 3, and it will be accompanied by a price reduction for the iPad mini 2 to $269.
