Yeah, I recently made the switch from Firefox to Chrome but I am pleased with it. My main selling point is how much faster it is on my system. It seems like a huge boost.
You know you can set it to open new windows as tabs, also?
I don't know anything about a WYSIWYG editor, so I can't speak to that.
Yeah, the switch killed my mouse gestures as well, but I found a program online that boots up with windows for mouse gestures. You create your own, so all I have to do to start Steam is make an S shape, or a V for Ventrilo, C for chrome, etc. It's pretty handy, and has a cut-off mode for gaming so you're not accidently opening programs while playing something.
It's called gMote. http://www.handform.net/gmote.php
