Pros
Pro Windows desktop style
The desktop UI was made to resemble Windows 7, but alternative settings are available.
Pro Definitely a good gaming OS (for the Lite-free version)
The 64x Lite edition is perfect for those gamers who want to move on from Windows, yet keep most of their game library.
It only uses *~700 MB of RAM, when idle.
Pro Ubuntu-based
Zorin is compatible with Ubuntu's sizable repositories of Free Software.
Cons
Con Violates freedom 0 for desktop layouts
They claim to be free as in freedom, but they're not free as in free beer, yet free beer is described in freedom 0, "freedom to use the software". Software that you can't make money off is considered nonfree because it's "discriminating against businesses", yet when you're doing the same discrimination on your users, it's considered ok. So what exactly are you paying for in Ultimate edition? Not new exclusive programs or anything, just "premium" desktop layouts.
Con Limited desktop styles in Free Version
All free editions only offer Windows XP, 2000, and 7 and Gnome 2. You have to pay $9-10 in order to get Unity (Ubuntu) and Mac OS X themes.
Con Slow in opening text files
Zorin is slow at opening text files, sometimes it can even take up to a few hours to open a text file.
