Latency is why I could never use a WYSIWYG word processor. While I don't like VI that much, it's latency is low enough that it's not a problem. i.e. I press a key, and miracle of miracles, the character appears on the screen. Using a WYSIWYG word processor, there's enough latency between keypress and visual update that I find them impossible to use. When Apple came out with Pages, it was apparent that they paid strong attention to latency. That means the latency is small enough that (for me) using it isn't an exercise in frustration.
