After installing RC I began to try a new way:
Dual-monitor, primary monitor on the left
Taskbar on the right, no autohide, big icon, no objectdock.
I think I will stay like this.
Just have to change my habits of searching start menu on the upper left corner
I'd love to be able to put the taskbar on the second monitor - left side (without put the right monitor as primary).
Shame that MS not support multimonitor more than the basics
