2015 or 2015?

October 21, 2015: two versions of Marty McFly will be roaming Hill Valley and hilarity will be experienced by all.  While Robert Zemeckis attempts to predict what 2015 will be like, he does get some things wrong.  Your task will be to compare and contrast 2015 to Zemeckis' fictionalized version.  It may be helpful to to discuss each of the 2015s individually in their own paragraphs and then discuss the similarities in a separate paragraph.  Remember that you need to write at least three hundred words and demonstrate good writing conventions.  Oh, and BE SPECIFIC!
