I'm not the person who you're responding to, but at least in my case I am just not comfortable with having the ability to switch, since I would like to connect devices which could be seriously damaged if the switch toggled for any reason. I have modified a couple of switchable power monitoring plugs already, but I would rather pay slightly less and not have a hassle.
IKEA's new smart plug to track power consumption could launch soon ( www.notebookcheck.net )
