things that aren't going to happen, like a truly single OS for all my "screens" being able to copy a text to the clickboard on my phone and pasting it on my computer, EVERY damn thing in sync, I mean everything, like having a Skype video call and being able to select my phone's camera if it is in wifi range, keeping every device connected to my homegroup so if I take a picture with my tablet I can see it instantly on my pics folder on any device, and if I start playing music on my pc my phone's music app should act as a remote as long as I have my pc's speakers as the output
well you get it, a marvel of software engineering that wont exist in the near future, even if it is obviously doable currently
