Stationary cell phone? (Score 3, Insightful)

So, what I would like to know is: why is there no cell phone specifically designed for home use? If the cellphone companies want us to get rid of landlines why have they not designed phones that can actually be used in a home environment?
I was a sucker for car phones: much better reception, easier to hold and work with than those tiny cellphones.
I want a 'stationary' cellphone for the house with an antenna on the roof for excellent reception so I don't have to use my tiny little cell phone.
