Sprint and Google heard those users' pain and has announced that soon, when you buy a new Android phone on Sprint, its number will be your Google Voice number too.
This method gets rid of that nasty porting and also applies to existing customers, which is a very nice way to expose new people to the service.
As landlines become more and more obsolete, and people start to have more than one mobile phone, it's nice to see companies such as Google and Sprint taking it into their own hands to make it easier for consumers to make the transition.
