I read it as 100 minutes to the PSTN - VoIP to normal phones. Skype has "unlimited" for $13 to several countries. That's because for the US, the average price is well under a penny, and for Canada it's a few tenths of a penny/minute. Many other countries also have fairly cheap rates.

So I'm confused as to why he'd compare a $12 100 minute plan to a $13 "unlimited" plan.
