For me personally, Skype is kicking it for real. Recently they released Skype Prime which is basically a payed service number (0900 in the Netherlands) but then for everyone and their mother: it is really easy to setup -no 3rd parties involved- and as such I think Skype will see a lot of Consumer to Consumer calls which is a space where a lot of people might want to participate.
