Traditional phone lines and TV going the way of the dodo?

Are we approaching the day when TV and phone lines are obsolete? Phone landlines are on the way to being obsolete. TV still has a significant amount of inertia to overcome, especially with DVRs so prevalent, but it could happen. I can already get all the services I would normally get from TV and a phone line from the Internet. They sometimes aren't as polished—if that can truly be said about some of the service my provider, Comcast, gives—as services that the incumbent companies give, but the Internet is increasingly approaching it.

Traditional Phones
The VoIP technology has existed for years, only in the last decade has it really taken off. Skype, MagicJack, Vonage, and many more companies have existed for about ten years. Even dedicated VoIP phones exist. Recently, Google has entered the VoIP market with Google Voice. Most notable about Google's offering is the price: free. The biggest perquisite with Google Voice is that I can use it while doing remote computer assistance without having to go buy a hands-free set for my phone as I already have a headset for my computer. Google Voice allows me to do everything I need or want to do with phone service through a web interface.

Edit before publishing:
I wrote this article, was about to publish it, and read a last minute post somewhere on the Internet about Google Voice requiring an existing phone subscription to work. Needless to say, more Googling ensued. It turns out that you do need a preexisting subscription with a traditional carrier for it to work, at least for all the features to work. I think it's ridiculous, but, perhaps, there are more ridiculous issues that require it when dealing with the very old thing we call a phone system.

Cell Phones
Cell phones have a few ways to drop the legacy voice connection. There have been a few movements to use nearby WiFi signals to route calls through the Internet. I'm not sure how successful or widespread those attempts have been. Another route is to use VoIP over the data connection instead of the normal voice stream. With no voice connection, phone numbers wouldn't be needed and could be dropped in favor for more recent addressing schemes. While there are enough phone numbers (so long as we look at all possible permutations and do not account for things like area codes) to allow for all phones to have a number, IPv6 could be used in place of phone numbers in a fully internet phone system. Using an IP address would allow the phones to call other phones directly and not have to use a "translator" or DNS like service to make calls. You could associate a single IPv6 address for each phone and could use another IPv6 address to "connect" as many phones as you want, similar to Google Voice's feature to ring six different phones when the Google Voice number called.

The only problem would be giving your IPv6 phone number to another person, let alone remembering it. I already have enough trouble with phone numbers, no way I could remember something like: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. However, that can be negated with software designed to share contact information or only using a subsection of the IPv6 space and reduce the amount of digits required. I'll stop rambling about IPv6 now; full implementation is still years off.

TV
Already, most TV networks have an online presence where you can watch TV episodes, not to mention the video giant Netflix is. Some of those venues have such long waiting periods for new material that there is no way to watch shows when they are relevant, but if you don't care about watching shows when they are the hottest thing, you'll be fine. There are other places to get the newest releases, but you have to "know where to look."

With TV being moved to the Internet, you no longer are bound to what the network thinks is a good time for your favorite show. While DVRs alleviate most of the scheduling issue, you can rarely play your shows where you want (e.g. on your computer), nor can you easily expand your DVR's storage. Internet TV has, effectively, unlimited storage and you can play shows when and where you want. Want to watch on your computer? Done. Your phone? It's easy if you have a fast enough data connection. Your TV? TVs are now coming with built-in web access and the Xbox 360 and PS3 already have Netflix access, they can be expanded to a new app; also, it is quite trivial to hook up your computer to your TV.

For the most part, I can do without phone and TV service from Comcast. I would have more difficulty splitting from my cell phone since I do not have a smartphone yet, but that can be fixed. Some barriers that need to be addressed before the Internet is my family's only media source are data caps and the relatively slow speed that internet connections seem to be stuck at. Both are an interconnected mess, each affects the other: with speeds not moving, caps will not increase; because of the low caps, users suppress their internet usage to the point that their speed doesn't matter.
