Desktops don't mean any of those things, crappy old computers with none of your characteristics are very common.
Technology has improved significantly in the 3 - 4 years since Motorola made theirs, and Ubuntu's failed as a crowdsourcing campaign. Nothing has been proven.
I interpreted Ubuntu's failure more a statement of lack of confidence in the ability of Ubuntu to execute on this idea than as a statement against the idea's ultimate potential.
Samsung, Google, Apple, or Nokisoft (MS+Nokia) could do it.
I think Microsoft could be in a position to do this with Windows 10. It certainly seems to me like it would be the next logical step after the Surface Pro.
