I need a large high resolution screen (4K 30" or better), a wireless keyboard and a wireless mouse. I need responsiveness to my inputs, so I need a local GPU and some local processing (pretty much where the web browser is headed), but most storage and computation could happen on the cloud and I wouldn't notice if the apps were written properly. My hope setup is already this for the most part: laptop + 4K monitor + wireless keyboard + wireless mouse. And I write applications and do CAD and 3D computer graphics. If I can live this way now, it means that most everyone else can too. Just need to continue to shrink that laptop down until it is just the size of a smart phone.
