I am thinking about getting rid of my landline at home, & sticking with just my cellphone. I would have to get a cable modem. Is a cable modem pretty equivilant to DSL? I pay $40 for the DSL & another $40-50 JUST for telephone service, & I am almost always using my cellphone. So if I could pay just $40 for a cable modem, & then pay for my cellphone, & say that $40-50 a month for phone service....well, that seems like a good deal to me.
