This thread is about whether Linux could be used by the average consumer, does GUI and the software exist to let the average user get the average tasks done, and the answer is a clear and resounding yes.
Yes but i think it would have to be preinstalled for the consumer (i've found hardware that still isn't supported) and would have to have a good amount of everyday software already installed for them.
I don't see the everyday consumer poping open the console to run a sudo get apt
which seemed to be the fastest way to get anything on a ubuntu computer.
I think from windows to linux would have a higher learning curve then say from mac to windows.
