BTW you still did not define the "modern apps" I asked about.
You really really have not thought this through. I am not saying UI does not matter, I am saying that in addition to UI the important thing is to have the device be extendible/customizable to the point that you can easily automate tasks, that you do not need to rely on functionality decided by manufacturers and application vendors. When you talk about "console" you seem to think that means using the console to launch functionality... When I talk about "console" I mean the whole works; functionality that does not need any UI to be useful; Just some examples;automatically immediately uploading any pictures I take to my gallery online recording all my calls backing the device up each night setting device mode based on the location I am currently tracking my location and updating that to my private online route map
So basically you are telling me that most people would need and prefer smartphone to compile kernel on it rather than having device using various services that ease your everyday life?
