From the Distrowatch web site, Robolinux is no longer requiring a purchase, in order to install it's Distro.
Robolinux comes with quite an extensive amount of built in programs including a large number of privacy programs (Tor, etc)
For an additional purchase price of $10 you can download a, Robolinux Stealth VM Software Installer, which will allow you to use your existing install of Window XP, Win7 or Win 10 and install it as a Virtual Machine, into your Robolinux Distro.

Cool. It looks like the Stealth VM is available as add-on for other distros, too.
That vm software installer is a nice feature, and worth the $10 if you have a Windows installation you want to convert. Other than that, are there any special features of Robolinux? Anyone tried it? Is this run by a single developer, or is there a team behind it with an active forum?
I don't know much about Robolinux other than it has been around probably for more than 5 years.
After I get my new SSD harddrive cloned with my existing Mint17.3 and Win7, that is currently on my Acer 1430, 11.6" notebook, than I may give Robolinux a try.
