I'm happy with Vodafone's cable broadband service so far and the d/u speed is great (120Mbps/10Mbps) but why couldn't Vodafone have issued a modem with an off/standby button?

I could switch it off from the mains when not in use or pull out the plug from the back of the modem but I think that might generate nasty voltage spikes.  This thing gives off warmth and I'm wondering how much it will add to my power bill?
