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 Even with v16 Pro, zero tech support replies
Do not pay for Pro. You’re supposed to get tech support with your $39 purchase. After contacting them a few months ago about the inability to install build tools due to their wonky custom versions, to date there has been no answer. You could find a friend and get them to send you the theme and look packages. The rest is all available easily in the Ubuntu catalog.
