Keep your mind out of the gutter guys!
Its a little doohickey that plugs into a USB port to which you plug your phone into. the jack plus one year costs 40 dollars, after that it is 20 dollars a year. No more phone bills. you can call anyone anywhere as long as you have the intenet for only 20 a year, or at least thats what they say.

Question: Has anyone used this device? If so, do you like it? What are the advantages and disadvantages?
