Gil,
Don't let dumb people get to you. You guys have done an amazing job and some people don't like change or learning new things..... at first. Yes, many people could get by without 3D, but hell, they could also get by without half of the effects that are available, but in the end, they will use it. Some people just like being negative. If people are making comments or judgments without totally understanding something, then they are idiots and should just keep their mouths shut.
BTW, you are a man of MANY talents!
