This will be my third review of the core version of Zorin OS.
I first reviewed Zorin 6 in July 2012 and looking back on that review it is clear that my posts were much shorter then than they are today.
One of the questions asked in that review was whether there was enough space for Zorin OS as it occupied similar space to Ubuntu and Linux Mint.
Zorin has survived a further two years since then but I find myself asking the same question because if anything there are more and more distributions with very similar offerings. Off the top of my head there is Ubuntu, Linux Mint, Netrunner, Kubuntu and PCLinuxOS.
