Canonical announces Ubuntu for the ARM platform

Fedora does not "like to break Nvidia drivers". That's a silly statement. When latest Xorg releases change the ABI, Fedora developers cannot fix the Nvidia proprietary driver to match the ABI change like they can and do for many of the other open source drivers including the open source Nvidia nv driver. Nvidia has a policy of waiting for a major distribution to include a new Xorg release in a distribution first before they update their proprietary drivers to match.

So either Fedora can wait for other distributions to include the latest Xorg release and get the blame for "breaking Nvidia drivers" or Fedora can go ahead and include it for the benefit of everyone. I think, the choice Fedora has made benefits everybody and there is no reason to hate them for it.
