I did this back in 2012 at university;

Talking about how smartphones could become primary computing devices for the majority of PC users in business (ofc not engineers that need CAD and rendering, or games developers, etc) through a dock which upscales the primary screen and lets you use a keyboard and mouse or the smartphone as a trackpad. How the rate of improvement in ARM CPUs was outpacing Intel, cloud computing, virtual PCs, etc.
Everyone thought I was crazy, bar the lecturers, but 4 years later in 2016 Microsoft is raving about Continuum which uses the smartphone as a primary computing device in business, the screen as a trackpad, Windows on ARM, etc. Think I hit the nail on the head with this one personally.
