However, if you want to talk about future capability, how about a mini PC (or whatever) that is permanently connected and monitoring activities in your home and abroad? If you have to connect your tablet to the docking station to attain a functional PC, then the docking station etc are devices with no functional capability in the meantime.
When we start to talk about connected homes, there has to be a resident PC or the like providing that permanent connection. It can't be your tablet that's in your backpack or whatever when away from home. That computer sitting at home may be programmed to undertake many functions, set the household temperature, monitor garden watering systems, security, feed the dogs, take a messages from doorknockers etc and provide you with an alert, and any number of other tasks.
