I think its over generalizing to depict extreme examples of Christianity that you learned about in the media. Irregardless of the flamewar in this thread, lets return to the topic at hand. Its the use of technology in congregation. While I believe we all have a right to worship how we see fit (and if you choose not to, that's your choice) lets put this in another context.
If you were in an assembled group of people for anything, be it a conference, some work related function, or even church, do you not think that technology has the ability to detract the attention span? Here you are with the boss, leader, or pastor presenting some sales pitch, training or sermon. While technology could be great at delivering visual aides and helping you reference things, it can also hinder your ability because you are shifting your attention and have the capability to become distracted. I can see some advantage in using technology to supplement a teaching, but I feel like you need balance to make that human connection.
