Why Keep Supposedly Landline Phone Service?

I would LOVE to get rid of my landline but I keep the it because

• Back in the Dark Ages, landline calls to 911 allow the operators to locate the physical location of the phone based on the 'the other end of the landline circuit.' I had erroneously believed that the landline will save a few seconds because 911 operators can look up the landline's physical address. This is no longer a good reason to retain a landline because e-911 has been implemented for mobile services as well as for VoIP phones. It might be harder for 911 operators to locate you, but they are able to do so.
• Starting back in the Dark Ages and continuing to today, credit card companies use the landline's caller ID to verify your identity. That use-case is fraught with security problems but it's still more convenient to activate credit cards by calling from the landline than going through the newer authentication hoops constructed by credit card companies.
• Service providers such as phone and cable companies have hidden landline fees into bundles of services such as Triple Play. Their pricing schemes make subscription fees for bundles lower than buying only the services you want, such as omiting the landline.
• Even though landlines aren't circuit switched anymore (no longer a dedicated circuit), they are actually VoIP, people erroneously believe that landlines are still dedicated lines and therefore provide more clear calls with fewer or no dropped packets. This is NOT TRUE. There is legislation in process to prohibit network managers from prioritizing service for marketing reasons -- meaning 'landlines' get higher network priority and therefore better call quality than, say, mobile calls.
• Calls made on the landline are 'sunken,' I've already paid for it whether I use it or not whereas if I use per-call fees for mobile calls, I save a little bit by using the landline instead of the mobile phone. Most people pay for both -- landline as well as monthly cell phone charges -- whether they use either phones at all. Why?

Many people have had the same landline number for years so they keep it for the convenience of their friends and vendors. I think nowadays, with web pages being constantly updated with no notice, people are more used to a continual flux. The deciding factor for whether to keep the same number is entirely based on how easy is its to 'migrate' or export your contacts to your new number.

I recently signed up for Google Voice. It's a step toward enabling anyone to reach me at any time, easily and for FREE. Thanks to VoIP (voice over internet protocol) advanced features, Google will connect anyone with me using any of the devices that I specified such as the landline, or the mobile phone, or both, or some other device, without revealing my phone number!
