Connectivity is something to be thinking about as a developer. Most people know expect to be connected to the Internet, to information, or to their applications. Whether via the phone, a tablet, or some other device, people are not expecting to be connected. What's more, it is now possible to be connected almost all the time. This connectivity will only get better as time goes on.
In an always connected world, how do your applications change? Things such as the Cloud start making a lot more sense when you start assuming connectivity.
