Operating systems have not been social in past years but recently Windows, Apple, and Android have been making their operating systems more social. How did they do this? Well Apple did it by adding the ability to post to facebook from the notification area. Android had the release of the Facebook phone which was a flop, Windows connects you to xbox live and any social media service you want all in one screen. But most recently Apple has released ios 7 which has the new air drop feature. This is the most social thing that I have seen in an operating system. It is basically Snapchat but better and it takes it a step further. It allows you to save pictures shared with you and you can share with as many people as you like. I think this feature makes ios 7 the most social os.
