So, just how many predictions about 2015 did "Back To The Future II" get right?

In the movie, Marty McFly of 2015 speaks to his colleagues on a video call – a fairly spot-on representation of how we chat using Skype or FaceTime. 

The characters also answered calls with glasses – similar to how computerized eye-wear Google glass works.

The film also sees a dehydrated pizza growing into a meal-sized dish after 12 seconds on the ‘hydrator plate’ – this could be seen as an early form of the microwave meal.
