Magic Jack is a gadget that you connect to your phone and plug into your computer. It supposedly offers lots of extras, and there are no long distance charges etc... The cost is $39.95 for the initial year and $19.95 per year after that. Can anyone tell me:

If this works well
If you sacrifice privacy for the convenience
Anything else you know or have heard about this or similar products.

Many thanks!
