I have had Skype Unlimited for a couple of months now. It is really sweet. I went to Phoenix for a week and took my computer. ---my desktop--
Once I was hooked up to the internet I hopped on Skype and called. It was great, the place I was staying did not have a land line but it did not matter to me.
When I got home it was the same story. As soon as I was hooked up to DSL I was making calls.
I paid $30 for one years access to outgoing calls with Skype Unlimited.
That is less than one month for a land line.
