iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
eWeek: Apple Tablet?
My sources sketch the following picture: A device that superficially resembles a large iPod with an 8-inch diagonal screen, lacks a keyboard, packs USB and FireWire ports, and runs Mac OS X along with a variety of multimedia goodies.
Matthew Rothenberg first "speculated" about this Apple tablet in November... but appears to have had some basis in circulating rumors.
Tablets are no new concept to Apple who designed prototype Newton tablets back in the early 90s.
