I have just installed Ubuntu10.10 alongside Fedora Core 15 and I am amazed at how fast the Gnome 2.32.0 desktop is compared to Gnome 3 and KDE 4.6. I had to install 370 MiB of updates with the sudo apt-get update && sudo apt-get upgrade command. This downloads the latest list of repository information and then downloads and installs all the required updates. Then I had to install the required codecs, so I typed sudo apt-get install ubuntu-restricted-extras to install all the restricted codecs and Adobe flash plugin to enable Youtube playback. Then you are all set. I have nothing against Ubuntu, but the releases after 11.04 are crap, the Unity desktop is not a nice and customisable interface like the older Gnome 2 desktop. At least Gnome 3 can be customised to look like Gnome 2.
This is the thing with Ubuntu, Canonical have sunk this Linux distribution, Ubuntu always was a nice Linux distribution, but now with the 12.04 release it is just a Macintosh Operating system look-alike. At least the MATE Gnome 2 fork will keep this desktop alive. And the Ubuntu 10.10 Maverick Meerkat distribution is very easy to install and configure. I like the CPU frequency scaling applet to underclock my CPU and keep it a little cooler. The problem with modern operating systems is the obsession with tablet platforms and the seeming need to design desktop operating systems to accommodate the tablet hardware, and neglect the use of the traditional keyboard and mouse.
