From the outside, Apple's 2015 13-inch MacBook Pro refresh is a minor one; the beautiful aluminium chassis and high resolution "Retina" display are identical to last year's model, and most of the changes are minor hardware specification increases. This is arguably a good thing, as the MacBook Pro is nothing short of iconic. The biggest upgrade is the addition of Force Touch, new touchpad technology (also found on the new 12in MacBook and the Apple Watch) the company hopes will change the way we interact with applications.
