I have a home phone primarily because I like the comfort of a handset that was made for phone conversation and nothing else. Although I've had some comfortable cellphones in the past (none recently), the heat from the radio and discharging battery made them uncomfortable for calls longer than 10 minutes.
I've been using VoIP for my home phone service, and it's been ideal. I can take it with me If I want to, and moving is a snap!
People who think they still have a twisted pair that reaches all the way back to the telco CO may be surprised to learn that ILECs are rapidly replacing copper with fiber, and installing tiny media convrsion points for the sake of cost (glass is cheaper) and for shorter DSL runs, which are the backbone of the ILEC version of the "triple play". Unlike a real CO with its large battery banks and Diesel generators, these micro points of presence have extremely limited backup power. A cellphone tower is far more likely to have a generator on-site!
IME, cable plants (which use the copper cables to distribute a lot of power) have stayed up with both TV and data after a storm has passed, and cellular service rarely drops out. And by using multipath (cable, DSL and cellular) to feed my VoIP phone, I get "five nines" reliability. It's no big deal for me since I have ample battery and generator power ready to go. If you don't already own the equipment to keep "five nines" at your end, your mileage may vary.
No matter what the connection, I still want a real handset that's ergonomic and doesn't slow-cook the side of my head during long calls, bottom line. (No pun intended.
