Really? So what you're saying is that any old Jane or Joe from off the street can go into their neighborhood electronics store, pick up a box of Linux and read the features list on the back, take it home and install it on their computer (any brand) and have it fully functional within an hour by just letting the installer do its job. It will go onto the internet to locate and download necessary drivers and install them automatically and essentially make itself fully consumer ready without anything more than the occasional click a yes/no button to start the next step.
That same user can then go back to the electronics store and pick up an office suite, games, photo or other consumer-grade application and install it with full functionality with no greater learning curve than what is available from MS or Apple.
Sorry, even Ubuntu still requires the user to have at least some understanding about how everything is supposed to work. The average consumer doesn't even want to know.
