@Ivan Like you I cannot understand why people are not open to informed debate and wish to shut it down. Listening to Roger made me laugh a times because as an engineer, he reminds me of many salesmen I have interacted with in the High Tech space. In my experience many of these guys all seem know enough about the tech "to be dangerous" but are in fact clueless when it comes to an in depth understanding of the the technical details. I think people should do their own research, listen to varied opinions and arrive at your own conclusions. Finally if you really feel that passionately about the issues become a coder not a troll.
