Phone Alternatives to Fat Cat Companies

CBC news reported today: Phone deregulation fails consumers Nothing really surprising here. I  must admit I do support one of the three fat cat phone companies-after all they employ one of my children.
What alternatives are there?
Briefly mentioned in this article (waaayy down at the bottom) are three newcomers to the Canadian telecommunications marketplace: Wind, Mobilicity and Public Mobile, but none has captured any substantial share of the market.
Another alternative mentioned in the comments by a reader is
“Majic Jack” a VOIP phone system.
Two online alternatives  I’ve used are calling from Skype and calling from Gmail . Skype is free to call computers, but gmail is free for landline calls too. The Google voice browser plug-in doesn’t work in Canada, but it is quite simple to call landlines for free  in Canada and the US from a gmail account. I have been told both of these have an echo on the other end, so I’ll need to try it with a mic and see if it works any better.
So in support of the little guys out there, here are links to their FAQ sites:
Wind
Mobilicity
Public Mobile
Majic Jack
Do you use one of the three fat cat phone companies or are you encouraging healthier competition in the marketplace?  What are your reasons?
