Skype now works with any home phone
Skype just got so easy your great-grandmother could use it without having to know anything about a sound card or any other input/output doohickeys that are more convoluted than President Harding and his confounding Teapot Dome scandal! (Look it up, millennials...)
Actually, there is one doohickey, but once it's all hooked up it looks an awful lot like a regular old cordless phone--with VoIP hidden inside. (No need to tell great-grandma about that last part, it will only confuse her--apologies to all technologically astute great-grandmothers out there, BTW.) It's the Freetalk ConnectMe home phone adapter for Skype, which connects to any regular old home phone.
