With the demise of the Ubuntu distribution as a viable desktop alternative to Windows; I am thinking that this is a good chance for those of us who want a proper desktop environment to change over to the Linux Mint distro instead. That offers the Gnome 2.32.2 fork MATE and there are codecs already in the distribution if you get the DVD version. I was trying out HyperV once and I installed Ubuntu 12.04 in that; but it did not work very quickly. VirtualPC is another virtualization tool for Windows 7 that I have had a look at. I used Crunchbang Linux in that and the installation was successful. But Virtualbox is my preferred tool as it has the Guest Additions and is very user friendly. Ubuntu 12.10 will not run very quickly in Virtualbox though. The Unity desktop is quite poor performance wise. I prefer Fedora on the desktop instead of Ubuntu as it has a very long legacy; beginning with the birth of the Red Hat Linux distribution in the 90s. So of course I enjoy using Fedora Core Linux. I still use the Debian distro on my laptop; with the MATE desktop now. That suits me fine.
Canonical want everyone to use Ubuntu on mobile devices instead; but with the amount of bugs in the distro; who would use this over iOS or Android? Just install Mint or Fedora and enjoy something that is actually usable. Linux offers freedom of choice; so just use something else.
Linux Mint: http://linuxmint.com/.
Fedora Linux: http://fedoraproject.org/.
Mateu: http://mateu.pt.vu/. A distribution based upon Ubuntu with the MATE desktop.
Crunchbang Linux: http://crunchbang.org/. A Linux distribution that uses the Openbox window manager.
Those are your alternatives to the Ubuntu 13.10 distribution. Goodbye Ubuntu and hello freedom.
