I think the usefullness of this product is based on what your usage is.

I agree that if you want to do a by the cheapest plan possible and split the minuts across 4 phones, then buy this and go with the unlimited plans, then you might come out ahead.

But otherwise this is a ripoff. I would gladly pay $100 for the device, I might even pay $5/month for the privilage of utilizing their voip servers to make unlimited calls. But once I have the device they are going to CHARGE me to use MY internet connect which I already pay for to route my calls over a VOIP network to their servers (thus bypassing the cost and load of using towers). So basically, I pay for my minutes (of cell tower use) and I pay for my internet, and Im going to pay them to use my internet to take the load off their systems.

Ya... this is definately targetted at people who arent intelligent enough to figure this out. Antenna and Amp here I come!
