James Duncan Davidson did the math and found he was better off without a land line phone:

Once the numbers have been looked it, however, it makes more sense to just go all the way. Of course, if $2400 per year was the only way to have decent access to the Internet, it’d be a different story. But it doesn’t need to cost that much anymore. So I’m cutting the twisted pair lines. Because, you know, they are historic and quant. Sure, a land line still sounds better than most mobile phone calls, but 3G calls are getting there in terms of clarity and on a good day sound as good to me as a land line. In a few years, they’ll be even better. Interestingly, I just got my phone bill from BT and am more glad than ever that I have a land line:

<th>
  Call Count
</th>

<td width="50%" style=" text-align: center;">
  13
</td>

<td width="50%" style=" text-align: center;">
  9
</td>

<td width="50%" style=" text-align: center;">
  4
</td>

<td width="50%" style=" text-align: center;">
  <strong>102</strong>
</td>

Nearly all of those international calls are an hour long by the way, about 16 hours per month on the phone. Total cost: £25/month. Try doing that with a mobile phone!

You could do it with VOIP which I’ve done in the past but the reliability is poor and the call quality is hit and miss.  With our land line we get consistently good connections and can use the phone without worrying about doing the tech support for it.

You know, the way life should be…
