The computer diffusion of innovation theory was quite an interesting topic. This lecture focused upon the five key factors that cause us to create and implement new technologies into our every day live, these five factors are: Relative advantage, compatibility & complexity, trialability, and observabitltiy. We discussed how the cell phones completed all five of these five factors with ease, causing society to innovate it into mainstream use. The relative advantage for cell phones is quite clear; being able to reach on at all times. This technology is very functional and simplistic for the most part, and is compatible with our other phone systems, so it is not difficult to access. As cell phones have dramatically evolved over the years is a result of its success in the field of trialablity and even today we have switched from analog to digital services, and these technologies will continue to evolve as we try out new alternatives. AS for the observability factor, well the vast majority of the students walking on campus have a cell phone super glued to their ears providing evidence that this technology has been successfully implemented.
