Compact size, vivid display, works with split-screen apps in iOS 9. Basically, a shrunken-down iPad Air 2. Perfect hand feel for vacations.Price is high for an 8-inch tablet. Slower graphics mean some apps and games don't feel as zippy. Small screen makes for cramped typing and multitasking.
Unless you're absolutely in love with the iPad Mini 4's smaller size, opt for the faster, larger, identically priced, and still pretty portable iPad Air 2.
