'Fedora download' named link is now obsolete.
As a suggestion, as a Linux/Solaris platform (in table), you may mention Centos as well.
As an enhancement suggestion regarding the following trivial issue: The contrast between links characters' colour (a kind of blue) and the background colour characters' colour (another kind of blue), is low enough so that such links are hardly visible (attachment) and as a result may be unnoticed at first sight. Would it be possible to create a sufficient contrast for a comfortable reading?
