I will never forget the first time a person tried to conduct a small conference in front of me on his computer. There were only four of us there, and we were seated quite comfortably around a small table. However, when he opened his laptop, there was no good way for all of us to see the screen at the same time. Depending on where you were sitting you could see some, all, or none of the screen because of the angles. It was also small even though we were a small group. I would definitely recommend that even small businesses that conduct conferences invest in audio visual projectors. It will save a lot of headaches during presentations.
