Apple Facetime versus Microsoft and Skype
Although Facebook and Apple have no official partnership, Apple doesn't, at this time, have a dog in the social media hunt. Skype and Facebook work on Apple computers and iPhones. Apple has a competing video calling application for iPhones called Facetime that some users say has better video quality than Skype. And Facetime is now a desktop application for Apple computer users as well.
But Facetime doesn't integrate with Facebook, and Skype's acquisition by Microsoft means every Windows PC user will soon be familiar with Skype. Once again, it's Microsoft versus Apple-but Skype has the Facebook advantage.
