You're absolutely right. Technical people would most likely embrace the switch. Everyone else will brush it off. I find that Americans are typically very cautious of any kind of change. Especially baby boomers. Let alone a change that is "imposed" by the rest of the world. That isn't going to fly here. We don't do things in the same way the rest of the world does them. That's just our mentality. Imagine a football field marked with metric units. Man, I just cringed a little bit. :)
