Powerpoint is one of the best ways to communicate ideas effectively, especially in the business world. Almost all of my classes have included a powerpoint presentation during the semester. There are many ways to present ideas and I believe that powerpoint is the most effective. You can include other programs with a powerpoint presentation such as Microsoft Word, or Excel or any of the other Microsoft created programs. Googledocs is another effective business tool and can be used to go "paperless."
The only problem with advancing technology so quickly is our reliance, as a society, on it. I think that a problem will occur if we rely 100% on new technology all of the time. Overall though, I see technology as a benefit as long as it is controlled.
