Ours. I have a cell phone, but this is for the home. Doesn't necessarily have to be overseas. Could be friends or families out of state.
It is beneficial in its own way. For example, If you have parents/inlaws who are older and does not have cell phones, then this would be ideal for them. Other than that, if you already have a cell phone and have a plan that allows you enough minutes for your use, then this wouldn't be useful at all. The other drawback is it relies soley on a broadband internet connection. Without it, it is useless as well.
the price/yr is very tempting, but if you add it all up, this will jsut be another debt you will have incur.
i have one and have been using it for the past year. The only beneficial reason for me is my mom is old and we live far from our relatives. This is a cheaper way for her to get in touch with the relatives since I am already paying for the internet service. I used to have a long distance carrier and it sucks balls with their plans.
