Telephone Voip Magic Jack actually bad for Environment?

Here is an interesting tibit or review about the popular telephone Magic Jack. They have sold millions around the world because of their very cheap telephone rates and setup (only 19.95 a year and 39.95 to buy it), also you get free long distance calling, free call forwarding, free call waiting, free call display etc.. but there is a drawback. You need to keep your computer on. Imagine all of these users leaving on their computers 24/7. How much energy does this drain? This is like an office building leaving on their lights at night when no one is in the office. Hopefully, most people still turn off their computers and just forward incoming calls to the cell phone or land lines. See for yourself below...cheers
