I have the feeling that among the ccTLDs the only one which will be considered to be one of the primary domains on the internet is .TV. Among ccTLDs it is the sole having a direct meaning, an international recognition, it is fashionable and taking into consideration broadband progress, the fact that internet is no longer static but grows more and more with interactive and dynamic content, the .TV seems to be very well positioned. In addition I would bet more on the attraction given by a .tv to the general public than the same name with .ws or .cc. Just ask around you with non-specialists and ask them to choose among cc.TLDs you will see their first reaction. See as just an exemple in the United States the real development of this extension registered by many different enterprises. Today not just the tv/video industry is registering .tv names. Although .TV reg fees are today very expensive I feel the .tv wave coming as an alternative to the stifling of the domain name market. Sure I am not a pro, for sure I am not rich, but prefer to invest my few dollars in this specific extension than in any other ccTLDS.
I do not know whether there could be a comparison between ccTLDS and real country names, ccTLDS are promoted as 'global' extensions and the others remain no matter what 'national' by definition. Keep in mind that some country names are available only for their nationals only, ccTLDS can be registered by anyone. It is obvious that the value of a domain name lays not only on its sole extension but on the quality of the name. Voila this just a personal opinion. Unless you got a good .com, a very good .net or .info, it is the big lottery but what's left in this great domain name quest is... passion !
