According to the CDC, as of June 2010 about 25% of US households have no wireline phone but have at least one mobile phone.

This comes up every election year because of the prevalence of phone based opinion polling. Younger people are more likely to not have a land line and thus not be polled, etc etc.

It costs more than twice than a landline and a 20Mbps connection.
Usually you're forced to get a landline if you want DSL. I've never seen a cable company force a landline on you. You can also get around the landline restriction from the phone company if you get a fiber connection though that's not offered in all areas.
That being said, we just moved and my wife just reminded me that neither of us actually know what the new number is - we've lived here for almost a month. So, we still rely on our cell phones.
Then the power went out.
Now, I had installed a battery backup sump-pump six months earlier, so that was able to keep up for a while. Our cell service also went in and out as the power outage was very large and our service at home was spotty (and the towers were over loaded). The only way for us to get ahold of family for help was through the land-line. I still keep at least one plugged in phone (non-cordless), just for this reason. Because of the land-line I was able to get my father-in-law to bring over a generator to power my sump-pump for the next day or so until our power was restored. Our basement had almost no water damage, mainly because we kept a land-line.
I haven't actually placed a call on my landline in about 5 years, so I figured there's no reason to keep it.
For people who don't have children (and even then…) and have a cell phone, I don't really see a good reason to still have a landline at this point.
I know that in France, for example, having a landline doesn't really cost you anything more than having the Internet, so most people have one. But $13 a month for nothing helps cutting that cord.
I haven't had a landline since 2004 but I'm considering getting one again. The reason is that neither my AT&T iPhone nor Skype via my AT&T DSL works all that great from my apartment. But I'm also looking at replacing my DSL modem/router in case that is why the DSL doesn't work. (That's what AT&T thinks is going on.)
Yes, it does. Calling 911 from a cell phone connects you to a big regional call center that gets your location and transfers you to your local one, whereas calling 911 from a land line connects you to your local emergency call center immediately.
Also, calling 911 from a land line gives the dispatcher your address. Cell phones will send along your location if they can get it, but GPS doesn't work too well indoors, and tower-based location can be off by tens or hundreds of meters.
As to the popularity, I know very few people young enough to have had a cell phone in high school who now have a landline. I know very few people outside of that group who don't.
Most of the over-25s I know (myself included) that don't have a landline ended up dropping it during a move.
Is having a landline so old-fashioned in the US? It's not the first time that I see this kind of comment, but it's shocking to me, since for most ISPs in many countries you must have a landline if you want some kind of Internet service, whether it's xDSL or cable.
