What are the Advantages of Having a Landline?

When your neighborhood loses power, your old telephone that doesn't require electricity still works. Without power, an IP phone won't work. If it lasts for a few days, your cell battery won't have power.

A short list is greater reliability than cell phones, easier to maintain (older people can use it easier than cell phones), better security (remember that person that was able to impersonate as a cell tower at that convention), better 911 location finding, almost no dropped calls by you (cause it is hard wired, no wireless interference), accessible during a power outage, and more

The advantages are fairly obvious. It is a phone. And a landline has clear sound and no dropped calls.

land lines are more reliable but voip is cheaper. (When I move out all I'm getting is internet and using my google voice/gmail to make calls)

Since VoIP is quite popular and you have services such as Google Voice & Skype, there aren't many advantages any more. The only one I can think of is if you have an old phone it will still work with the power out (Also, the only advantage of dial-up if you have a laptop)

In most places within the USA, there are laws in effect that protect how long primary phone lines can be down. It's related to 911 Emergency Call Systems, I believe?!?

Reliability a VOIP telephone may work if the power goes out as long as you have its power source being a UPS but the UPS battery will eventually lose its charge.

If you live down in a place where you barely get service, like me, a landline will be better. At my house, you can stand one place and barely get service, and then you take one step, you don't get service anymore, no matter what cell phone service you use. And I am not walking a quarter of a mile just to get service and make a call. All my neighbors have landlines too.

Also, another advantage I can think of is that some places only accept calls from landlines.

I really don't use cell phones. I don't even have one. But if I were to get one, I would have it as paid by the minute rather a monthly cost. Because I would only use it for emergencies. I don't know if cell phones cause cancer or not, but it's always good to be on the safe side.
